Features
— Three-cycle latency, one-cycle throughput, double-precision add
— Four-cycle latency, two-cycle throughput, double-precision multiply-add
System unit
— Executes CR logical instructions and miscellaneous system instructions
— Special register transfer instructions
Load/store unit
— One-cycle load or store cache access (byte, half-word, word, double word)
— Effective address generation
— Hits under misses (one outstanding miss)
— Single-cycle unaligned access within double-word boundary
— Alignment, zero padding, sign extend for integer register file
— Floating-point internal format conversion (alignment, normalization)
— Sequencing for load/store multiples and string operations
— Store gathering
— Cache and TLB instructions
— Big- and little-endian byte addressing supported
Level 1 cache structure
— 32K, 32-byte line, eight-way set-associative instruction cache (iL1)
— 32K, 32-byte line, eight-way set-associative data cache (dL1)
— Cache locking for both instruction and data caches, selectable by group of ways
— Single-cycle cache access
— Pseudo least-recently-used (PLRU) replacement
— Copy-back or write-through data cache (on a page per page basis)
— MEI data cache coherency maintained in hardware
— Nonblocking instruction and data cache (one outstanding miss under hits)
— No snooping of instruction cache
Level 2 (L2) cache interface (not implemented on MPC745)
— Internal L2 cache controller and tags; external data SRAMs
— 256K, 512K, and 1 Mbyte two-way set-associative L2 cache support
— Copy-back or write-through data cache (on a page basis, or for all L2)
— Instruction-only mode and data-only mode
— 64-byte (256K/512K) or 128-byte (1M) sectored line size
— Supports flow through (register-buffer) synchronous BurstRAMs, pipelined (register-register)
synchronous BurstRAMs (3-1-1-1 or strobeless 4-1-1-1) and pipelined (register-register) late
write synchronous BurstRAMs
— L2 configurable to cache, private memory, or split cache/private memory
— Core-to-L2 frequency divisors of ÷1, ÷1.5, ÷2, ÷2.5, and ÷3 supported
— 64-bit data bus
