The CMOS/SOS Microsignal Processor (µSP) is a 12-bit general purpose programmable, pipelined signal processor designed to efficiently perform digital filtering and processing algorithms. The architecture of the µSP is built of three elements - control, arithmetics, and memory: control consists of a sequencer and address generator; arithmetics consist of a scaler/shifter, 12 x 12 multiplier, a dual ALU and multipart memories; and Data memory consists of commercial 4K memory chips. Programmability is achieved through a stored program which calls and implements desired micro instructions in the arithmetic pipeline. A typical µSP can be programmed to implement various length complex or real FFTs, perform correlation/convolution, and sundry vector operations and digital filtering tasks. For example, the three architecture elements - control, memory and arithmetics operate in parallel to per-form a 1024 pt complex FFT in 3 ms (memory to memory). A typical CMOS/SOS µSP is designed for single chip carriers grouped into six hybrid types and fit onto one two-sided 6 in. by 9 in. module. The µSP is designed to be T2L interface compatible and operate at 10 V with 30-35 W of power dissipation. This paper will present the background leading to the design, describe the architecture and discuss the CMOS/SOS chips involved in the design.
