A programmable real-time video signal processing LSI (HD-Picot) has been developed, which has an architecture suitable for the video-rate processing of signals, including both conventional TV and high definition TV. It processes video signals at a speed of 37.125MHz and with 24 bit precision, employing reconfigurable pipeline structure, sophisticated program-control system, and syncronization mechanism between processors. It has two input ports, one output port, two arithmetic logic units, two arithmetic units, two multipliers, two variable delays, and two ports for an external data memory of 2 MBytes. It can calculate address, access (read or write) data memory, and process data simultaneously. The LSI was made with 0.8μm CMOS gate array technology.
