PC7447A

Preliminary

Description

The PC7447A host processor is a high-performance, low-power, 32-bit implementa-

tions of the PowerPC

Reduced Instruction Set Computer (RISC) architecture

combined with a full 128-bit implementation of Freescale

’s AltiVec

™

technology.

This microprocessor is ideal for leading-edge embedded computing and signal pro-

cessing applications. The PC7447A features 512 KB of on-chip L2 cache. The

PC7447A microprocessor has no backside L3 cache, allowing for a smaller package

designed as a pin-for-pin replacement for the PC7447 microprocessor. This device

benefits from a silicon-on-insulator (SOI) CMOS process technology, engineered to

help deliver tremendous power savings without sacrificing speed. A low-power version

of the PC7447A microprocessor is also available.

Figure 1-1 on page 2

shows a block diagram of the PC7447A. The core is a high-per-

formance superscalar design supporting a double-precision floating-point unit and a

SIMD multimedia unit. The memory storage subsystem supports the MPX bus proto-

col and a subset of the 60x bus protocol to the main memory and other system

resources.

Note that the PC7447A is a footprint-compatible, drop-in replacement in a PC7447

application if the core power supply is 1.3V.

PC7447A [Preliminary]

2. Features

This section summarizes features of the PC7447A implementation of the PowerPC architecture.

Major features of the PC7447A are as follows:

• High-performance, superscalar microprocessor

– Up to four instructions can be fetched from the instruction cache at a time

– Up to 12 instructions can be in the instruction queue (IQ)

– Up to 16 instructions can be at some stage of execution simultaneously

– Single-cycle execution for most instructions

– One instruction per clock cycle throughput for most instructions

– Seven-stage pipeline control

• Eleven independent execution units and three register files

– Branch processing unit (BPU) features static and dynamic branch prediction

128-entry (32-set, four-way set-associative) branch target instruction cache (BTIC),

a cache of branch instructions that have been encountered in branch/loop code

sequences. If a target instruction is in the BTIC, it is fetched into the instruction

queue a cycle sooner than it can be made available from the instruction cache.

Typically, a fetch that hits the BTIC provides the first four instructions in the target

stream.

2048-entry branch history table (BHT) with two bits per entry for four levels of

prediction: not taken, strongly not taken, taken, and strongly taken

Up to three outstanding speculative branches

Branch instructions that do not update the count register (CTR) or link register (LR)

are often removed from the instruction stream

Eight-entry link register stack to predict the target address of Branch Conditional to

Link Register (BCLR) instructions

– Four integer units (IUs) that share 32 GPRs for integer operands

Three identical IUs (IU1a, IU1b, and IU1c) can execute all integer instructions except

multiply, divide, and move to/from special-purpose register instructions.

IU2 executes miscellaneous instructions including the CR logical operations, integer

multiplication and division instructions, and move to/from special-purpose register

instructions.

– Five-stage FPU and a 32-entry FPR file

Fully IEEE

754-1985-compliant FPU for both single- and double-precision

operations

Supports non-IEEE mode for time-critical operations
