Development of a multichip module DSP

The signal processor packaging design (SPPD) general-purpose digital signal processor (DSP) architecture is discussed. SPPD is a highly modular processor architecture that is based on off-the-shelf components and that supports a multichip module (MCM) design implementation that delivers 400 million floating-point operations per second in a 75-g package. The interconnect-substrate design, MCM package assembly, MCM testing, and tradeoffs in size, weight, and cost of the SPPD packaging are described.<
