PPC740 and PPC750 Hardware Specifications
3 of 43
2.0 Features
This section summarizes features of the PPC740’s and PPC750’s implementation of the
PowerPC architecture. Major features are as follows:
Branch processing unit
-- Four instructions fetched per clock
-- One branch processed per cycle (plus resolving 2 speculations)
-- Up to 1 speculative stream in execution, 1 additional speculative stream in
fetch
-- 512-entry branch history table (BHT) for dynamic prediction
-- 64-entry, 4-way set associative branch target instruction cache (BTIC) for
eliminating branch delay slots
Dispatch unit
-- Full hardware detection of dependencies (resolved in the execution units)
-- Dispatch two instructions to six independent units (system, branch,
load/store, xed-point unit 1, xed-point unit 2, or oating-point)
-- Serialization control (predispose, post dispatch, execution, serialization)
Decode
-- Register le access
-- Forwarding control
-- Partial instruction decode
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 misaligned access within double word boundary
-- Alignment, zero padding, sign extend for integer register le
-- 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
-- Misaligned little-endian support in hardware
Fixed-point units
-- Fixed-point unit 1 (FXU1); multiply, divide, shift, rotate, arithmetic, logical
-- Fixed-point unit 2 (FXU2); shift, rotate, arithmetic, logical
-- Single-cycle arithmetic, shift, rotate, logical
-- Multiply and divide support (multi-cycle)
-- Early out multiply
Floating-point unit
-- Support for IEEE-754 standard single- and double-precision oating-point
