PowerPC 740 and PowerPC 750 Embedded Microprocessor

IBM CMOS 0.20 um Copper Technology EMPPC740L and EMPPC750L

Features

This section summarizes features of the implementation of the PowerPC 750 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, ﬁxed-point unit 1,

ﬁxed-point unit 2, or ﬂoating-point).

- Serialization control (predispatch, postdispatch, execution, serialization).

• Decode

- Register ﬁle 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 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.

- 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.
