80960 Processor Core
The 80960Jx family is a scalar implementation of the 80960 core architecture. Intel designed this
processor core as a very high performance device that is also cost-effective. Factors that contribute
to the core’s performance include:
•

SRC1
Core operates at the bus speed with the 80960JA/JF/JS
Core operates at two or three times the bus speed with the 80960JD/JC and 80960JT,
respectively
Single-clock execution of most instructions
Independent Multiply/Divide Unit
Efficient instruction pipeline minimizes pipeline break latency
Register and resource scoreboarding allow overlapped instruction execution
128-bit register bus speeds local register caching
Two-way set associative, integrated instruction cache
Direct-mapped, integrated data cache
1-Kbyte integrated data RAM delivers zero wait state program data
