Research and Critically Review three General-Purpose Embedded Processors - Essay Example This essay stresses that microprocessors came into existence with the advent of computer technology. Since then, there has been a steep increase in the technological advancement with each new technology replacing the old counterpart in a matter of a year or two. Power consumption and dissipation, among these processors, was not a cause of concern as the issue could be easily addressed by use of fans with processors to keep them cool apart from providing an air conditioned environment. This arrangement sounds good for desktop applications only, while mobile applications warrants good performance in open environment with stored power sources (batteries) and no cooling mechanism. This paper declares that embedded microprocessors have a number of associated properties and features of which the following five offer best criteria for differentiating and estimating the performance. CISC processors exhibit better code density than RISC processors due to complex instruction set in CISC, while RISC utilizes a fixed length instruction code. However the RISC architecture offers simple and fast instruction decoding. It is not always advisable to integrate a large number of peripherals and chipsets with the processor. This would increase complexity and may not lead to desired results. It may further, create power consumption problems. A possible way out could be a separate chipset for applications.
