An event-driven massively parallel fine-grained processor array

A multi-core event-driven parallel processor array design is presented. Using relatively simple 8-bit processing cores and a 2D mesh network topology, the architecture focuses on reducing the area occupation of a single processor core. A large number of these processor cores can be implemented on a single integrated chip to create a MIMD architecture capable of providing a powerful processing performance. Each processor core is an event-driven processor which can enter an idle mode when no data is changing locally. An 8x8 prototype processor array is implemented in a 65 nm CMOS process in 1,875um x 1,875um. This processor array is capable of performing 5.12 GOPS operating at 80 MHz with an average power consumption of 75.4 mW.
