A 24-Bit Block Floating Point Digital Signal Processor

A CMOS 24-bit Block Floating Point Digital Signal Processor chip for Sonar applications is described. The device integrates data and program memory, two arithmetic processing elements, and address generator in a single chip providing a performance improvement of up to ten times that available using standard DSP devices for Sonar signal processing. The device has been implemented on a 1.4 micron two layer metal CMOS process.
