MPC860 Family Hardware Specifications
MOTOROLA
Features
MPC8xx core that incorporates memory management units (MMUs) and instruction and
data caches and that implements the PowePC instruction set. The communications
processor module (CPM) from the MC68360 QUICC has been enhanced by the addition of
the inter-integrated controller (I
2
C) channel. The memory controller has been enhanced,
enabling the MPC860 to support any type of memory, including high-performance
memories and new types of DRAMs. A PCMCIA socket controller supports up to two
sockets. A real-time clock has also been integrated.
Table 1 shows the functionality supported by the members of the MPC860 family.
Part II Features
The following list summarizes the key MPC860 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 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.
