Embedded Systems

RATIONALE:

Increasingly, embedded systems developers and system-on-chip designers select specific microprocessor cores and a family of tools, libraries, and off-the-shelf components to quickly develop embedded system-based products. A major processor in this industry is ARM. Since 1985, the ARM architecture has become the most pervasive 32-bit architecture in the world. ARM processors are embedded in products ranging from cell/mobile phones to automotive braking systems. A worldwide community of ARM partners and third-party vendors has developed among semiconductor and product design companies, including hardware engineers, system designers, and software developers. This course has been to describe the operation of the ARM core from a product developer’s perspective with a clear emphasis on its architecture by assuming no previous ARM experience.

OBJECTIVES:

•

On successful completion of the course, the students must be able to

•

Distinguish between CISC and RISC architecture

•

Understand the ARM design philosophy

•

Explain the ARM architecture and the pipeline structure

•

Describe the little and big endian methods of representation

•
