combines 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 ?s. The MSP50C30
features two independent channels of linear predictive coding (LPC), which synthesize high-quality Speech
at a low data rate. Pulse-code modulation (PCM) can produce music or sound effects. For more information, see the MSP50C30
User?s Guide (literature number SPSU012).
