Features
The major features of the MPC8272 are as follows:
Dual-issue integer (G2_LE) core
— A core version of the MPC603e microprocessor
— System core microprocessor supporting frequencies of 266-400 MHz
— Separate 16-Kbyte data and instruction caches:
– Four-way set associative
– Physically addressed
– LRU replacement algorithm
— PowerPC architecture-compliant memory management unit (MMU)
— Common on-chip processor (COP) test interface
— Supports bus snooping for cache coherency
