80960KA EMBEDDED 32-BIT MICROPROCESSOR s High-Performance Embedded Architecture — 25 MIPS Burst Execution at 25 MHz — 9.4 MIPS* Sustained Execution at 25 MHz s 512-Byte On-Chip Instruction Cache — Direct Mapped — Parallel Load/Decode for Uncached Instructions s Multiple Register Sets — Sixteen Global 32-Bit Registers — Sixteen Local 32-Bit Registers — Four Local Register Sets Stored On-Chip — Register Scoreboarding s 4 Gigabyte, Linear Address Space s Pin Compatible with 80960KB The 80960KA is a member of Intel’s i960® 32-bit processor family, which is designed especially for embedded applications. It includes a 512-byte instruction cache and a built-in interrupt controller. The 80960KA has a large register set, multiple parallel execution units and a high-bandwidth burst bus. Using advanced RISC technology, this high performance processor is capable of execution rates in excess of 9.4 million instructions per second*. The 80960KA is well-suited for a wide range of applications including non-impact printers, I/O control and specialty instrumentation. s Built-in Interrupt Controller — 31 Priority Levels, 256 Vectors — 3.4 µs Latency @ 25 MHz s Easy to Use, High Bandwidth 32-Bit Bus — 66.7 Mbytes/s Burst — Up to 16 Bytes Transferred per Burst s 132-Lead Packages: — Pin Grid Array (PGA) — Plastic Quad Flat-Pack (PQFP) SIXTEEN 32-BIT GLOBAL REGISTERS 64- BY 32-BIT LOCAL REGISTER CACHE 32-BIT INSTRUCTION EXECUTION UNIT INSTRUCTION FETCH UNIT 512-BYTE INSTRUCTION CACHE INSTRUCTION DECODER MICROINSTRUCTION SEQUENCER MICROINSTRUCTION ROM 32-BIT BUS CONTROL LOGIC 32-BIT BURST BUS Figure 1.
