The creation and consumption of cool gadgets has become a way of life for many designers, engineers, and billions of consumers. These gadgets, whether for music, video, Web navigation, games, or communications, keep getting ever more sophisticated, smarter and smaller.

ColdFire integrated enhanced multiply accumulate (eMAC) unit as a fundamental function block. Many algorithms of DSP processing and cryptography heavily rely on add and multiply operations, which can be boosted with MAC and eMAC.

Freescale plans to demonstrate systems featuring processors built on Power Architecture and StarCore technologies, including the MSC8156 digital signal processing (DSP), which has been named an IEC InfoVision award finalist.

Most multiprocessing systems can be classified as either symmetric multiprocessing (SMP) or asymmetric multiprocessing (AMP).

I will focus on DSP (digital signal processing) on FPGA to see the advantages and disadvantages.DSP (digital signal processing) is implied in some specific applications where the necessary filter order is too high or the computation scheme is too complex for analog circuit implementation. Analog signal filtering in the discrete domain can be done with the use of a simple processing chain, containing an analog-digital converter (ADC), a computation unit that can be a DSP, an FPGA either a personal computer, and a digital-analog converter. In this article I will concentrate on a processing chain with an FPGA and describe the advantages and disadvantages of it.
