Features
— Monitors all dispatched instructions and retires them in order
— Tracks unresolved branches and flushes instructions after a mispredicted branch
— Retires as many as three instructions per clock cycle
Separate on-chip L1 instruction and data caches (Harvard architecture)
— 32-Kbyte, eight-way set-associative instruction and data caches
— Pseudo least-recently-used (PLRU) replacement algorithm
— 32-byte (eight-word) L1 cache block
— Physically indexed/physical tags
— Cache write-back or write-through operation programmable on a per-page or per-block basis
— Instruction cache can provide four instructions per clock cycle; data cache can provide four
words per clock cycle
— Caches can be disabled in software.
— Caches can be locked in software.
— MESI data cache coherency maintained in hardware
— Separate copy of data cache tags for efficient snooping
— Parity support on cache
— No snooping of instruction cache except for icbi instruction
— Data cache supports AltiVec LRU and transient instructions
— Critical double- and/or quad-word forwarding is performed as needed. Critical quad-word
forwarding is used for AltiVec loads and instruction fetches. Other accesses use critical
double-word forwarding.
Level 2 (L2) cache interface
— On-chip, 1-Mbyte, eight-way set-associative unified instruction and data cache
— Cache write-back or write-through operation programmable on a per-page or per-block basis
— Parity support on cache tags
— ECC or parity support on data
— Error injection allows testing of error recovery software
Separate memory management units (MMUs) for instructions and data
— 52-bit virtual address, 32- or 36-bit physical address
— Address translation for 4-Kbyte pages, variable-sized blocks, and 256-Mbyte segments
— Memory programmable as write-back/write-through, caching-inhibited/caching-allowed, and
memory coherency enforced/memory coherency not enforced on a page or block basis
— Separate IBATs and DBATs (eight each) also defined as SPRs
— Separate instruction and data translation lookaside buffers (TLBs)
– Both TLBs are 128-entry, two-way set-associative and use an LRU replacement algorithm.
– TLBs are hardware- or software-reloadable (that is, a page table search is performed in
hardware or by system software on a TLB miss).
