Embedded Processing Cores

14.1 Overview

Processors are one of the most flexible components in an embedded designer’s toolbox. Processor design flexibility has evolved through hardware and software standardization and technology advancements. The reduced instruction set computer (RISC) is arguably one of the most commonly implemented processor architectures. Popular examples of RISC-based processors include PowerPC™, ARM™ and MIPS™. Along with the RISC architecture, robust software tools and high-level programming languages have enabled the use of processors in almost every conceivable type of embedded system.

SRAM-based FPGA flexibility can be further enhanced by embedding processors within the FPGA component. The embedded processor ...
