The 80960CF, object code compatible with the 32-bit
80960 core Architecture, employs Special Function
Register extensions to control on-chip peripherals
and instruction set extensions to shift 64-bit
operands and configure on-chip hardware. Multiple
128-bit internal buses, on-chip instruction caching
and a sophisticated instruction scheduler allow the
processor to sustain execution of two instructions
per clock with peak execution of three instructions
per clock.
A 32-bit demultiplexed and pipelined burst bus
provides a 132 Mbyte/s bandwidth to a system’s
high-speed external memory subsystem. Also, the
80960CF’s on-chip caching of instructions, proce-
dure context and critical program data substantially
decouples system performance from the wait states
associated with accesses to the system’s slower,
cost sensitive, main memory subsystem.
The 80960CF bus controller integrates full wait state
and bus width control for highest system perfor-
mance with minimal system design complexity.
Unaligned access and Big Endian byte order support
reduces the cost of porting existing applications to
the 80960CF.
