Overview

The ColdFire V4 core delivers exceptional performance - more than 500 MIPS - while maintaining a low cost and small size. Upward compatibility from ColdFire V1, V2 and V3 cores provides a smooth roadmap to higher performance designs, giving customers exceptional design flexibility.

The ColdFire V4 core can provide over 500MIPs of performance using a standard cell-based design methodology in a generic 90-nm process technology and interfaces to the System-on-Chip (SoC) using the standard AMBA-AHB bus. The core supports a variable-length RISC architecture that allows instructions to be 16, 32 or 48 bits in length. The result is more efficiently packed code in memory, reducing memory requirements and lowering overall system cost. All ColdFire cores (V1, V2, V3 and V4) share the same architecture and instruction set, making upward compatibility to other ColdFire cores a smooth roadmap to higher performance designs.

Standard Product Platform–SPP To help designers decrease time to market, Freescale has packaged the ColdFire V4 core architecture into a Standard Product Platform (SPP). The SPP is a set of tested and previously deployed sub-systems and peripherals easily used to build large complex systems. It has been designed to share the same peripheral set included on many ColdFire standard devices, leveraging the extensive peripheral portfolio to enhance end-use applications with the latest features and capabilities.

Standard Product Platform–SPP

To help designers decrease time to market, Freescale has packaged the 68K/ColdFire V2 core architecture into a standard product platform. The SPP is a set of tested and previously deployed subsystems and peripherals easily used to build large, complex systems.SPP Features• V2 ColdFire core—100–160 MHz

Key Features

The ColdFire® 4 microarchitecture provides a 2.8x performance improvement when compared with the ColdFire 3 core over a broad range of applications.

Improved microarchitecture for higher performance: greater than 200 Dhrystone 2.1 MIPS @ 150 MHz
Small set of new instructions for better code density and performance
Enhanced MAC and debug functionality
Core size = 4.5 mm2 in 0.25 micron drawn process
Independent, decoupled pipelines
4-stage Instruction Fetch Pipeline (IFP)
5-stage Operand Execution Pipeline
FIFO I-Buffer is the decoupling mechanism
Limited superscalar execution through use of instruction folding
Approaches dual-issue performance but at a much lower silicon cost
Harvard memory architecture
Most instructions execute in 1 cycle
Sophisticated 2-level branch acceleration mechanisms in the IFP minimize execution time of change
