General DescriptionThe TD1501 is a of easy to use adjustable step-down (buck) switch-mode DC/DC converter. The device is available in an adjustable or fixed output version. It is capable of driving a 3A load with excellent line and load regulation.The output voltage is guaranteed to ±3% tolerance under specified input voltage and output load conditions. The oscillator frequency is guaranteed to ±15%.The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%. External shutdown is included, featuring typically 80 µA standby current. Self protection features include a two stage frequency reducing current limit for the output switch and an over temperature shutdown for complete protection under fault conditions. Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation, and a fixed-frequency oscillator.The TD1501 is available in TO-220B-5L and TO-263-5L packages.

A suitable input bypass capacitor must be present at this pin to minimize voltage transients and to supply the switching currents needed by the regulator.GNDCircuit ground.OutputInternal switch. The voltage at this pin switches between (+V IN – V SAT) and approximately – 0.5V, with a duty cycle of approximately V OUT / V IN. To minimize coupling to sensitive circuitry, the PC board copper area connected to this pin should be kept a minimum.FeedbackSenses the regulated output voltage to complete the feedback loop.ON/OFFAllows the switching regulator circuit to be shutdown using logic level signals thus dropping the total input supply current to approximately 80uA. Pulling this pin below a threshold voltage of approximately 1.3V turns the regulator on, and pulling this pin above 1.3V (up to a maximum of 32V) shuts the regulator down. If this shutdown feature is not needed, the ON /OFF pin can be wired to the ground pin , the regulator will be in the ON condition. The ON /OFF pin should not be left open .Functional Block DiagramFigure 2. Functional Block Diagram of TD1501Typical ApplicationFigure 3.

The TO-220B/TO220 package needs a heat sink under most conditions. The size of the heatsink depends on the input voltage, the output voltage, the load current and the ambient temperature. The TD1501 junction temperature rises above ambient temperature for a 3A load and different input and output voltages. The data for these curves was taken with the TD1501 (TO-220B/TO220 package) operating as a buck switching regulator in an ambient temperature of 25o C (still air). These temperature rise numbers are all approximate and there are many factors that can affect these temperatures. Higher ambient temperatures require more heat sinking.The TO-263 surface mount package tab is designed to be soldered to the copper on a printed circuit board. The copper and the board are the heat sink for this package and the other heat producing components, such as the catch diode and inductor. The PC board copper area that the package is soldered to should be at least 0.4 in2, and ideally should have 2 or more square inches of 2 oz. Additional copper area improves the thermal characteristics, but with copper areas greater than approximately 6 in2, only small improvements in heat dissipation are realized. If further thermal improvements are needed, double sided, multilayer PC board with large copper areas and/or airflow are recommended.The TD1501 (TO-263 package) junction temperature rise above ambient temperature with a 3A load for various input and output voltages. This data was taken with the circuit operating as a buck switching regulator with all components mounted on a PC board to simulate the junction temperature under actual operating conditions. This curve can be used for a quick check for the approximate junction temperature for various conditions, but be aware that there are many factors that can affect the junction temperature. When load currents higher than 3A are used, double sided or multilayer PC boards with large copper areas and/or airflow might be needed, especially for high ambient temperatures and high output voltages.For the best thermal performance, wide copper traces and generous amounts of printed circuit board copper should be used in the board layout. (Once exception to this is the output (switch) pin, which should not have large areas of copper.) Large areas of copper provide the best transfer of heat (lower thermal resistance) to the surrounding air, and moving air lowers the thermal resistance even further. Output Voltage Ripple and TransientsThe output voltage of a switching power supply will contain a sawtooth ripple voltage at the switcher frequency, typically about 1% of the output voltage, and may also contain short voltage spikes at the peaks of the sawtooth waveform.The output ripple voltage is due mainly to the inductor sawtooth ripple current multiplied by the ESR of the output capacitor.The voltage spikes are present because of the fast switching action of the output switch, and the parasitic inductance of the output filter capacitor, To minimize these voltage spikes, special low inductance capacitors can be used, and their lead lengths must be kept short. Wiring inductance, stray capacitance, as well as the scope probe used to evaluate these transients, all contribute to the amplitude of these spikes.A large value inductor will also result in lower output ripple voltage , but will have a larger physical size,higher series reistance,and/or lower saturation current. An additional small LC filter can be added to the output (as shown in Figure 14) to further reduce the amount of output ripple and transients.Layout GuidelinesAs in any switching regulator, layout is very important. Rapidly switching currents associated with wiring inductance can generate voltage transients which can cause problems. For minimal inductance and ground loops, the wires indicated by heavy lines should be wide printed circuit traces and should be kept as short as possible. For best results, external components should be located as close to the switcher IC as possible using ground plane construction or single point grounding.If open core inductors are used, special care must be taken as to the location and positioning of this type of inductor. Allowing the inductor flux to intersect sensitive feedback, IC groundpath and C OUT wiring can cause problems.When using the adjustable version, special care must be taken as to the location of the feedback resistors and the associated wiring. Physically locate both resistors near the IC, and route the wiring away form the inductor especially an open core type of inductor.Figure 14, Layout Guidelines and Post Ripple FilterTDxxxxxTDxxxxxPackage Information (TO220B-5L)Dimensions In Millimeters Dimensions In Inches SymbolMin.

字子瞻,号东坡居士。

宋代眉州(今四川省眉山市)人。

父苏洵、弟苏辙都是著名古文学家,世称“三苏”。

嘉佑进士,任凤翔府签判,主张改革弊政。

神宗时反对变法,但在密州、徐州任上抗洪灭蝗,赈贫救孤、颇多政绩。

苏轼的词大都抒写仕途坎坷的感慨,也有反映民生疾苦、揭露现实黑暗之作。

苏轼是宋代文化孕育出来的旷世奇才,历经磨难而笑对人生,思想自由、品格坚贞、坦荡旷达,其文如行云流水,行于所当行,止于不可不止;其诗如天地奇观,于境无所不收,于情无所不畅;其词如天风海雨逼人,指出向上一路。

无论从哪个方面衡量,他都是宋文学发展到尖峰时期的伟大的代表作家。

苏轼词作历来颇受尊崇。

苏轼对词的贡献很突出。

苏轼出现前,词的内容受传统念束缚,局限于旖旎温柔的艳情腻语的范围之内;苏轼则吊古伤今、述电咏怀、感叹时政,描绘山川景色、农村风光,以至谈论哲理等题材都进入了词中,大大开拓了词的题材与意境,为宋词的民展打开了新的局面。

ELEC6236Digital System Design Assignment2020/21Prof Mark ZwolinskiNovember20,20201ObjectiveThe objective of this assignment is to design an adder for two32-bitfloating point numbers. Y our design should be written in SystemVerilog and must simulate and synthesise correctly. Y our code will be assessed automatically–by compiling your SystemVerilog code and running it through the design tools.Half of the marks for this assignment(10)will be awarded for passing tests.Y ou must also complete a short report,describing what you have done.The other half of the marks(10)will be for this report.This assignment is designed to test your ability to write correct SystemVerilog code and to use the design tools.The assignment is worth20%of the module marks and should therefore take you about30hours to complete.Y ou may discuss the assignment with other students,but the code that you submit for as-sessment must be your own work.Please ensure you are familiar with the rules on academic integrity and the penalties for violating those rules.2Specification2.1Floating-point formatIEEE Standard754defines the format offloating point numbers.For this assignment,numbers should be represented in the32-bit form(also known as binary32):Bit31–Sign bit,0for positive numbers,1for negative numbers.Bits30-23(8bits)–Signed exponent.This is a power of2,biased by127.For example,the pattern011111002is12410.This represents the value124-127=-3,so the mantissa(see below) is multiplied by2−3.Bits22-0(23bits)–Mantissa.This is the fractional part of the number.There is an assumed leading1,which is not stored.Example(from Wikipedia):0.1562510is represented in binary as0.001012(that is,1/8+ 1/32).This can be written as1.012×2−3.As we have seen,the exponent,−3is stored as 127−3=12410=011111002.The mantissa is stored as010000000000000000000002–the leading1is not stored,it is assumed.The sign bit is0.2.2AdderY ou are asked to design an adder that takes two normalized32-bitfloating point numbers and adds them to give a normalized result.Y our adder should handle the‘special’numbers:zero, positive and negative infinity and‘Not a Number(NaN)’.Y ou do not have to consider other special cases.Y ou may use either‘round to zero’(truncation)or‘round to nearest’.Although it is possible,in principle,to design this as a combinational circuit,you must design a sequentialcircuit.There is no upper limit to the number of cycles that may be taken,so long as the design meets the timing requirements given in the next section.Hints:To add twofloating point numbers,it is necessary to adjust one number so that the exponents of the two numbers are the same.So,to do this,thefields of eachfloating point number(sign,mantissa,exponent)need to be extracted,the implicit leading1of each mantissa needs to be restored.If the mantissa of a number is shifted left or right,the exponent for that number is decremented or incremented by one,respectively.This form of afloating point number is known as a denormalized number.One of the mantissas(which one?)needs to be shifted(which way?)until the exponents of the twofloating point numbers are the same. The mantissas are then added or subtracted,according to the sign bits.The resulting number then has to be normalized.Although denormalized numbers are allowed under some circumstances,in this case returning a denormalized number would be wrong(why?).2.3TimingY our design must be synchronous.The system must be sensitive to the positive edge of the clock(only).Y ou should include an active low asynchronous reset that will set the contents of all registers to0.Y our adder must have a‘ready’output.This should be asserted for one clock cycle only.The adder has one32-bit input bus and one32-bit output bus.When the‘ready’signal is asserted, the adder expects thefirst input on the next clock cycle and the second input on the one after that.The sum is available in the same clock cycle as the‘ready’signal.In other words,a new calculation can begin as soon as the previous calculation is complete.3AssessmentY our design will be simulated with a testbench that will use some test cases.First,the reset will be tested.Then some‘corner cases’will be tried.For example:•0.0+0.0=0.0•0.0+1.0=1.0•−1.0+1.0=0.0The adder will then be tested with some arbitrary numbers.Y our design will be scored for each test that is passed.The sum output must be correctly normalized–you will get no marks for a result that does not conform to the IEEE standard.The design will then be validated with Verilator and Quartus.Marks will be deducted for warnings or errors that would cause the design to be synthesised incorrectly.4SubmissionY ou must submit twofiles.Thefirstfile,fpadder.sv,contains your code.This may contain more than one module;the header of the main module must be as follows:module fpadder(output logic[31:0]sum,output logic ready,input logic[31:0]a,input logic clock,nreset);Y ou must also submit a brief report of2pages,Design Report.pdf.Y ou can create this PDF file using either the Word or Latex templates provided.Please check that the PDFfile opens correctly in Acrobat.Y ou may submit multiple versions of your SystemVerilog code and thefinal report.Only the last version will be assessed.The code in thefinal submission will be automatically marked. The code in yourfirst5submissions only will also be automatically marked and the score for these submissions will be emailed back to you,but the scores will not be part of thefinal assessment.The deadline for submission is16:00on T te submissions will be penalised in line with ECS regulations.Please ensure that your reportfile is included with your final submission.Appendix:Behavioural ModelThe following code is a functionally-equivalent,behavioural model of the adder.Y ou can use this to verify your design,by comparing the bit pattens.This model completes in one clock cycle–your design is likely to require more cycles–but meets the timing specification.Note.Y ou must not use the real or shortreal types in your design.All submitted de-signs will be checked for these types before simulation and if the test fails,will not be simulated or synthesised.In other words you will receive zero marks.module fpadder_behav(output logic[31:0]sum,output logic ready,input logic[31:0]a,input logic clock,nreset); //to allow inputs to be loaded in successionenum{start,loada,loadb}state;shortreal rsum,ra;//shortreal is32bit floating pointalways@(*)sum=$shortrealtobits(rsum);//converts real to bitsalways@(*)ra=$bitstoshortreal(a);//converts bits to realalways@(posedge clock,negedge nreset)if(˜nreset)beginrsum<=0;state<=start;endelsebegin//This is a state machine,but there are other ways to do this case(state)start:beginstate<=loada;endloada:beginrsum<=ra;state<=loadb;endloadb:beginrsum<=rsum+ra;state<=start;endendcaseendalways@(*)ready=(state==start);endmoduleAn outline testbench can be used to simulate this design–and yours. module test_fpadder;logic[31:0]sum;logic ready;logic[31:0]a;logic clock,nreset;shortreal reala,realsum;fpadder_behav a1(.*);initialbeginnreset=’1;clock=’0;#5ns nreset=’1;#5ns nreset=’0;#5ns nreset=’1;forever#5ns clock=˜clock;endinitialbegin@(posedge clock);//wait for clock to start@(posedge ready);//wait for ready@(posedge clock);//wait for next clock tickreala= 1.0;a=$shortrealtobits(reala);@(posedge clock);reala=-2.0;a=$shortrealtobits(reala);@(posedge ready);realsum=$bitstoshortreal(sum);$display("%f\n",realsum);endendmodule。

22515 Computer Based Accounting:Assignment 3Due: N o later than 5.00pm on Friday 7th June 2013.As with all assignments in this subject, students MUST incorporate their NAME – (SURNAME & INITIALS) with the business name. Assignments where students name appear in hand written form, will attract a zero mark.IntroductionCorporation law and accounting standards require that companies and other reporting entities, prepare financial statements according to prescribed content and format. Such reporting capabilities are not available in MYOB and in similar accounting packages.
