VR5432  
64-Bit MIPS RISC Microprocessor  
The VR5432ä microprocessor brings a new level of high-end performance to low-cost  
embedded design. This member of NEC’s VR Seriesä microprocessors operates at either  
167 or 200 MHz and uses a gated clock, minimal switching techniques, and a special circuit  
design to keep power consumption low. Its symmetric dual-issue pipeline with six  
independent execution units executes any combination of arithmetic logic unit (ALU), floating-  
point, or rotate instructions, while 32 KB instruction and data caches implement cache line  
locking to keep critical code and data cached. Multiple outstanding read transactions allow  
both caches to be filled concurrently, keeping the processor supplied with a steady stream of  
instructions and data. Mapping of accesses to virtual memory addresses is optimized with a  
48-double-entry joint instruction/data translation lookaside buffer (TLB) and two separate  
four-entry micro TLBs for instructions and data.
