The MSP50x3x family uses a revolutionary architecture to combine an 8-bit microprocessor,
two speech synthesizers, ROM, RAM, and I/O in a low-cost single-chip system. The
architecture uses the same arithmetic logic unit (ALU) for the two synthesizers and the
microprocessor, thus reducing chip area and cost and enabling the microprocessor to do a
multiply operation in 0.8 us. The MSP50x3x family features two independent channels of linear
predictive coding (LPC), which synthesize high-quality speech at a low data rate. Pulse-code
