RM7000™ Superscalar

Dual-Issue Microprocessor

with On-Chip L2 Cache

FEATURES

• Dual Issue symmetric superscalar microprocessor with instruc-

tion prefetch optimized for system level price/performance

— 200, 225, 250, 263, 300 MHz operating frequency

— >500 Dhrystone 2.1 MIPS @ 300 MHz

• MIPS IV Superset Instruction Set Architecture

— Data PREFETCH instruction allows the processor to overlap

cache miss latency and instruction execution

— Single-cycle floating-point multiply-add

— 14.6-14.8 SPECint95, 14.8-17 SPECfp95 @ 300 MHz

• Integrated memory management unit

— Fully associative joint TLB (shared by I and D translations)

— 64/48 dual entries map 128/96 pages

— Variable page size

• High-performance system interface

— 1000 MB per second peak throughput

— 125 MHz max. freq., multiplexed address/data

— Supports two outstanding reads with out-of-order return

— Processor clock multipliers 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 7, 8, 9

• Embedded application enhancements

— Specialized DSP integer Multiply-Accumulate instruction,

(MAD/MADU) and three-operand multiply instruction (MUL/

MULU)

• Integrated primary and secondary caches - all are 4-way set

associative with 32 byte line size

— 16KB instruction, 16KB data, 256KB on-chip secondary

— Per line cache locking in primaries and secondary

— I&D Test/Break-point (Watch) registers for emulation &

debug

— Performance counter for system and software tuning &

debug

— Fourteen fully prioritized vectored interrupts - 10 external, 2

internal, 2 software

• Integrated external cache controller (up to 8M Bytes)

• High-performance floating-point unit - 600 M FLOPS maximum

— Single cycle repeat rate for common single-precision opera-

tions and some double-precision operations

• Fully static CMOS design with dynamic power down logic

— Standby reduced power mode with WAIT instruction

— 3.3 watts typical @ 2.5V Int., 3.3V I/O, 200MHz

— Single cycle repeat rate for single-precision combined multi-

ply-add operations

— Two cycle repeat rate for double-precision multiply and dou-

ble-precision combined multiply-add operations

• RM5271 pin compatible, 304 pin SBGA package, 31x31mm
