This paper gives an overview of the existing approaches to the hardware/software codesign of embedded systems. We discuss all the steps in the design trajectory. The common approach of adding dedicated hardware to accelerate the software (by way of a FPGA or ASIC coprocessor) is judged as not worth the effort. The multi-processor framework of ASIPs (application specific instruction set processo...

Embedded systems are computer systems used as components in other systems. It is a very broad field encompassing a large number of very different requirements, and the computer architecture of embedded systems reflects this variation by a large degree of specialization to application areas.

this paper surveys parallel scheduling problems and metrics correlated to and then applys metrics to make decision in comparison to other policy schedulers. parallel processing is new trend in computer science especially in embedded and multicore systems whereas needs more power consumption to reach speed up. the qos requirement for users is to have good responsiveness and for service providers...
