2 Features

The following list summarizes the key MPC860 features:

•

Embedded single-issue, 32-bit PowerPC core (implementing the PowerPC architecture) with

thirty-two 32-bit general-purpose registers (GPRs)

— The core performs branch prediction with conditional prefetch without conditional execution.

— 4- or 8-Kbyte data cache and 4- or 16-Kbyte instruction cache (see Table 1)

– 16-Kbyte instruction caches are four-way, set-associative with 256 sets; 4-Kbyte instruction caches

are two-way, set-associative with 128 sets.

– 8-Kbyte data caches are two-way, set-associative with 256 sets; 4-Kbyte data caches are two-way,

set-associative with 128 sets.

– Cache coherency for both instruction and data caches is maintained on 128-bit (4-word) cache

blocks.

– Caches are physically addressed, implement a least recently used (LRU) replacement algorithm, and

are lockable on a cache block basis.

— MMUs with 32-entry TLB, fully-associative instruction, and data TLBs

— MMUs support multiple page sizes of 4-, 16-, and 512-Kbytes, and 8-Mbytes; 16 virtual address spaces

and 16 protection groups

— Advanced on-chip-emulation debug mode

Up to 32-bit data bus (dynamic bus sizing for 8, 16, and 32 bits)

32 address lines

•

Operates at up to 80 MHz

Memory controller (eight banks)

— Contains complete dynamic RAM (DRAM) controller
