64-Bit Superscaler Microprocessor
Features
s Full militarized QED RM5261 microprocessor
s Dual Issue superscalar microprocessor - can issue one
integer and one floating-point instruction per cycle
q 133, 150, 200, 250 MHz operating frequencies – Consult Factory
for latest speeds
q 345 Dhrystone 2.1 MIPS
q SPECInt95 7.3, SPECfp95 8.3
s Pinout compatible with popular RM5260
s High performance system interface compatible with RM5260,
RM 5270, RM5271, RM7000, R4600, R4700 and R5000
q 64-bit multiplexed system address/data bus for optimum price/
performance
q High performance write protocols maximize uncached write
bandwidth
q Supports 1/2 clock divisors (2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 7, 8, 9)
q IEEE 1149.1 JTAG boundary scan
s • Integrated on-chip caches
q 32KB instruction - 2 way set associative
q 32KB data - 2 way set associative
q Virtually indexed, physically tagged
q Write-back and write-through on per page basis
q Pipeline restart on first double for data cache misses
s • Integrated memory management unit
q Fully associative joint TLB (shared by I and D translations)
q 48 dual entries map 96 pages
q Variable page size (4KB to 16MB in 4x increments)
s High-performance floating point unit: up to 500 MFLOPS
q Single cycle repeat rate for common single precision operations
and some double precision operations
q Two cycle repeat rate for double precision multiply and double
precision combined multiply-add operations
q Single cycle repeat rate for single precision combined multiply-
add operation
s • MIPS IV instruction set
q Floating point multiply-add instruction increases performance in
signal processing and graphics applications
q Conditional moves to reduce branch frequency
