| Abstract(in English) | Cool Mega Array or CMA is a low power reconfigurable processor array for battery driven mobile devices. We developed a prototype chip CMA-1. It is consisting of 8×8 PE array and μ-controller for controlling data alignment. We just borrowed the network of a dynamically reconfigurable processor for CMA-1, and sufficient examination about it has not been carried out so far. Also, the overhead of the configuration data transfer time to CMA-1 appeared to bottleneck the system performance. It means that the amount of configuration data for PE array should be as small as possible . In this paper, we evaluated three types of PE array network for CMA, which can archive better energy efficiency with a small amount of configuration data. As a result, in CMA-const which has island style networks and dedicated links for sending constants, we could reduce the number of steps for transferring configuration data by 44.4 % on average, 53.8 % at most without a negative influence on performance and power of CMA. |
