Front-End Design of Task Compiler for Reconfigurable Multimedia Processor

In order to automatically map algorithms onto reconfigurable multimedia processor and improve the parallel efficiency of algorithms,a task compiler front-end is designed.The kernel loop unrolling is introduced to improve the degree of parallelism;and the scalar replacement technique based on data dependence analysis is used to optimize the cost of data transmission.Experiments show that the task compiler front-end improves the degree of parallelism effectively,its performance can be,compared with the front-end of Garp C compiler,sharply increased up to 2～4 times in the whole system.
