| Abstract: | A multi-core based multimedia system developed with ESL platform was introduced.Using ARM ESL,the whole system was profiled.The partitions and the architecture were obtained.In addition,hardware and software co-operation at the system level to achieve real-time system were optimized which was able to decode multimedia streams in different formats.This method provides a means to accelerate embedded systems,as well as other multi-core applications like PCs,with a certain degree of universality. |
| Keywords: | ESL multimedia SMP decode embedded system |
