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:
•
•
•
•
•
•
•

CLKIN
Local Register Cache
TAP
SRC1
Core operates at the bus speed with the 80960JA/JF
Core operates at two or three times the bus speed with the 80960JD 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
