Design of data-path for a VLIW media coprocessor

A design study of data-path for a VLIW media coprocessor is presented. The VLIW coprocessor executes the kernels in media applications, and has great impact on the performance of the media processor. To explore the architecture tradeoff at early stage, we proposed three architecture models, and hand scheduled three typical kernels onto the models, with the instruction set simulator, we evaluated architecture by evaluating the instruction level behavior of the architecture models, so that the data-path can be adapted to kernel programs.
