Freescale Semiconductor
Overview
1Overview
The MPC862/857T/857DSL is a derivative of Freescale’s MPC860 PowerQUICC family of devices. It
is a versatile single-chip integrated microprocessor and peripheral combination that can be used in a
variety of controller applications and communications and networking systems. The
MPC862/857T/857DSL provides enhanced ATM functionality over that of other ATM-enabled members
of the MPC860 family.
Table 1 shows the functionality supported by the members of the MPC862/857T/857DSL family.
2Features
The following list summarizes the key MPC862/857T/857DSL features:
Embedded single-issue, 32-bit MPC8xx 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 cache (MPC862P) is four-way, set-associative with 256 sets; 4-Kbyte
instruction cache (MPC862T, MPC857T, and MPC857DSL) is two-way, set-associative
with 128 sets.
– 8-Kbyte data cache (MPC862P) is two-way, set-associative with 256 sets; 4-Kbyte data
cache (MPC862T, MPC857T, and MPC857DSL) is 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
