2 / 80 page  MPC860 Family Hardware Specifications, Rev. 7 2 Freescale Semiconductor 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 Table 1.
