EMBEDDED SYSTEM DESIGN

EMBEDDED SYSTEM DESIGN

ABSTRACT

The ability to have many functional blocks on-chip is a requirement for designers today. When looking at all the new technologies and emerging design tools available, one knows that these tools have made it easier to architect systems with these new solutions. New leading-edge applications ranging from games to networking infrastructure equipment are driving the need to include large-capacity and high-speed memory on-chip rather than separately as a discrete device.

This paper discusses the need of SoC in the embedded technology, there by focusing the attention on the reduced power consumption of the devices and looking forward to the integration of the hardware and the software applications on a single chip without affecting the functionality of the output with SoC solutions. Over the past decade, one of the more interesting advancements in embedded technology has been the move toward system-on-a-chip (SoC) implementations. The migration of discrete components into a single-chip footprint enables designers to take advantage of the cost, power, and speed that just aren’t available in other equivalent multi-chip systems.

This paper also gives brief review over the Advances in System-on-Chip (SoC) technology which makes it possible to utilize customizable embedded processor cores, together with a variety of novel on-chip/off-chip memory hierarchies, allowing customization of SoC architectures for specific embedded applications and tasks.

INTRODUCTION:

SoC’s are nothing but System on Chip, whose designs are becoming increasingly popular in the embedded system arena. Integration of a fully functional system in a single chip demands integration of hardware and related software. For the system integrator, the benefits of high integration include faster time to market, lower power consumption, higher reliability, and lower cost. The semiconductor industry is meeting the demands presented by the market trends with System-On-a-Chip (SoC) designs. Any SoC contains the processor, logic, analog macros and memory needed to perform all of the critical functions& they also represent a major departure from previous system-on-a-board development. Today, thanks to advancements in embedded technology, these architecture have lead us to an era of super integration which not only integrates DSP and the processor but also results in many System On a Chip (SoC) solutions that make embedded systems hardware design very easy.
