allowing the R2000 core to proceed without stalling itself. In the absence of cache misses, this chip set sustained an instruction completion rate of one instruction per ALU cycle. This was more efficient than non-RISC microprocessors of that time, which needed several cycles per instruction. The initial R2000A, clocked at 12.5 MHz, offered 8-10 Million integer
Instructions Per Second (MIPS), or 0.9 Million FLoating Point Operations Per Second (MFLOPS), and would appear in the like of the 1987
79:
The chip set consisted of the R2000 microprocessor, R2010 floating-point accelerator, and four R2020 write buffer chips. The core R2000 chip executed all non-floating-point instructions with a simple short pipeline. This chip also controlled the external code and data caches, made of fast standard
84:
for mapping virtual memory addresses. The R2010 chip held the floating point registers, floating point data paths, and their longer simple pipeline. Writes to main memory DRAM took tens of cycles to fully complete. But the R2020 chips queued and completed up to 4 pending writes to main memory,
108:
Overall speed was limited by the cache size and cache cycle time. The R2000 chip set and SRAM was initially sold only as a complete circuit board to ensure good cache bus timings. In 1987 system builders began using the chip set in arbitrary new board designs.
135:
LSI fabricated the chip set in its 2.0 μm double-metal CMOS process and marketed it as the LR2000. Performance
Semiconductor fabricated the chip set in its PACE-I 0.8 μm double-metal CMOS process and marketed it as the PR2000.
139:
In 1988, an improved version was introduced, the R2000A. It was composed of the R2000A and R2010A ICs. It operated at 12.5 and 16.67 MHz. It has been used extensively in embedded applications such as printer controllers.
112:
The R2000 was available in 8.3, 12.5 and 15 MHz grades. The die contained 110,000 transistors and measured 80 mm in a 2.0 μm double-metal CMOS process. MIPS was a
