ColdFire Module Description
1.3.1.2 Operand Execution Pipeline (OEP)
The prefetched instruction stream is gated from the FIFO buffer into the five-stage OEP.
The OEP consists of two, traditional two-stage RISC compute engines with a register file
access feeding an arithmetic/logic unit (ALU). The compute engine located at the top of the
OEP is typically used for operand memory address calculations (the address ALU), while
the compute engine located at the bottom of the pipeline is used for instruction execution
(the execution ALU). The resulting structure provides 3.9 Gbytes/S data operand
bandwidth at 162 MHz to the two compute engines and supports single-cycle execution
speeds for most instructions, including all load, store, and most embedded-load operations.
In response to users and developers’ comments, the V4 design supports execution of the
ColdFire Revision B instruction set, which adds a small number of new instructions to
improve performance and code density.
The OEP also implements two advanced performance features. It dynamically determines
the appropriate location of instruction execution (either in the address ALU or the execution
ALU) based on the pipeline state. The address compute engine, in conjunction with register
renaming resources, can be used to execute a number of heavily-used opcodes and forward
the results to subsequent instructions without any pipeline stalls. Additionally, the OEP
implements instruction folding techniques involving MOVE instructions so that two
instructions can be issued in a single machine cycle. The resulting microarchitecture
approaches the performance of a full superscalar implementation, but at a much lower
silicon cost.
1.3.1.3 MAC Module
The MAC unit provides signal processing capabilities for the MCF5407 in a variety of
applications including digital audio and servo control. Integrated as an execution unit in the
processor’s OEP, the MAC unit implements a three-stage arithmetic pipeline optimized for
16 x 16 multiplies. Both 16- and 32-bit input operands are supported by this design in
addition to a full set of extensions for signed and unsigned integers, plus signed, fixed-point
fractional input operands.
1.3.1.4 Integer Divide Module
Integrated into the OEP, the divide module performs operations using signed and unsigned
integers. The module supports word and longword divides producing quotients and/or
remainders.
1.3.2 Harvard Architecture
A Harvard memory architecture implements separate instruction and data buses to the
processor-local memories, removing conflicts between instruction fetches and operand
accesses.
