It has a high performance 64-bit integer unit, a high throughput, fully pipelined 64-bit floating point unit, an operating system friendly memory management unit with a 48-entry fully associative TLB, a 16 KByte 2-way set associative instruction cache, a 16 KByte 2-way set associative data cache, and a high-performance 64-bit system interface. The ACT5260 can issue both an integer and a floating point instruction in the same cycle.The ACT5260 is ideally suited for high-end embedded control applications such as internetworking, high performance image manipulation, high speed printing, and 3-D visualization.HARDWARE OVERVIEWThe ACT5260 offers a high-level of integration targeted at high-performance embedded applications. Some of the key elements of the ACT5260 are briefly described below. Superscalar DispatchThe ACT5260 has an efficient asymmetric superscalar dispatch unit which allows it to issue an integer instruction and a floating-point computation instruction simultaneously. With respect to superscalar issue, integer instructions include alu, branch, load/store, and floating-point load/store, while floating-point computation instructions include floating-point add, subtract, combined multiply-add, converts, etc. In combination with its high throughput fully pipelined floating-point execution unit, the superscalar capability of the ACT5260 provides unparalleled price/performance in computationally intensive embedded applications.CPU RegistersLike all MIPS ISA processors, the ACT5260 CPU has a simple, clean user visible state consisting of 32 general purpose registers, two special purpose registers for integer multiplication and division, a program counter, and no condition code bits. PipelineFor integer operations, loads, stores, and other non-floating-point operations, the ACT5260 uses the simple 5-stage pipeline also found in the circuits R4600, R4700, and R5000. In addition to this standard pipeline, the ACT5260 uses an extended seven stage pipeline for floating-point operations. Like the R5000, the ACT5260 does virtual to physical translation in parallel with cache access.Integer UnitLike the R5000, the ACT5260 implements the MIPS IV Instruction Set Architecture, and is therefore fully upward compatible with applications that run on processors implementing the earlier generation MIPS I-III instruction sets. Additionally, the ACT5260 includes two implementation specific instructions not found in the baseline MIPS IV ISA but that are useful in the embedded market place. Described in detail in the QED RM5260 datasheet, these instructions are integer multiply-accumulate and 3-operand integer multiply.The ACT5260 integer unit includes thirty-two general purpose 64-bit registers, a load/store architecture with single cycle ALU operations (add, sub, logical, shift) and an autonomous multiply/divide unit. Additional register resources include: the HI/LO result registers for the two-operand integer multiply/ divide operations, and the program counter(PC). Register FileThe ACT5260 has thirty-two general purpose registers with register location 0 hard wired to zero. These registers are used for scalar integer operations and address calculation. The register file has two read ports and one write port and is fully bypassed to minimize operation latency in the pipeline.ALUThe ACT5260 ALU consists of the integer adder/ subtractor, the logic unit, and the shifter. The adder performs address calculations in addition to arithmetic operations, the logic unit performs all logical and zero shift data moves, and the shifter performs shifts and store alignment operations. Each of these units is optimized to perform all operations in a single processor cycleFor additional Detail Information regarding the operation of the Quantum Effect Design (QED) RISCMark™ RM5260™, 64-Bit Superscalar Microprocessor see the latest QED datasheet (Revision 1.1 July 1998).Absolute Maximum Ratings1Symbol Rating Range Units V TERM T erminal Voltage with respect to GND-0.52 to 4.6V Tc Operating T emperature-55 to +125°C T BIAS Case T emperature under Bias-55 to +125°C T STG Storage T emperature-55 to +125°CI IN DC Input Current203mAI OUT DC Output Current50mA Notes:1.
