In this paper, we propose a dynamically reconfigurable processor Array (DRPA) generator which can generate various types of DRPAs. Our target DRPA architecture is fully parameterized. By specifying architectural parameters, it can automatically generate RTL model, simulation environment, and finally chip layout. In our DRPA generator, although the fundamental design of a processing element (PE) and an inter-PE connection is fixed, the array size, PE granularity, and connection flexibilities of intra/inter PE are selectable. In this paper, we have generated various types of DRPAs and evaluated semiconductor area and speed by using the AS-PLA/STARC 90-nm CMOS technology. From evaluation results, fundamental trade-offs between architectural parameters and area/delay are analyzed.
