Features
2Features
The following list summarizes the key MPC860 features:
Embedded single-issue, 32-bit PowerPCTM 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
