Research of Embedded Computer Performance Evaluation Technology

Closely related to its application and the market,the embedded system design is subjected to many factors,such as the cost,power dissipation,chip area,and the development cycle.Meeting the given required performance of a embedded system design,there is no need to make a larger margin of the system performance design.In a product development cycle,the key point to make a project success is to design a performance satisfied system in a lower material cost and lower development cost.For this reason,it is necessary to make an evaluation and analysis in the embedded micro-processor and entire embedded system for gist of the system performance design.In this paper,by introducing the principle and methods used in the embedded system performance evaluation,describing the several Benchmarking and their applicability.And then,by analyzing the application case of those Benchmarking,with regard to the need of early performance evaluation in embedded system level design,introducing an E3S Benchmark and the system level performance evaluation methods,and giving a prospect of the embedded system design performance evaluation methods.
