description
The MSP50C614 (C614) is a low-cost, mixed-signal processor that combines a speech synthesizer,
general-purpose I/O, onboard ROM, and direct speaker-drive in a single package. The computational unit
utilizes a powerful new DSP which gives the C614 unprecedented speed and computational flexibility compared
with previous devices of its type. The C614 supports a variety of speech and audio coding algorithms, providing
a range of options with respect to speech duration and sound quality.
The device consists of a micro-DSP core, embedded program and data memory, and a self-contained clock
generation system. General-purpose periphery is comprised of 64 bits of partially configurable I/O.
The core processor is a general purpose 16 bit micro-controller with DSP capability. The basic core block
includes computational unit (CU), data address unit, program address unit, two timers, eight level interrupt
processor, and several system and control registers. The core processor gives the C614 break-point capability
in emulation.
The processor is Harvard type for efficient DSP algorithm execution. It requires separate program and data
memory blocks to permit simultaneous access. It is configured in 32K 17-bit words.
The total ROM space is divided into two areas: 1) The lower 2K words are reserved by Texas Instruments for
the purposes of a built-in self-test 2) The upper 30K is for user program/data.
The data memory is internal static RAM. The RAM is configured in 640 17-bit words. Both memories are
designed to consume minimum power at a given system clock and algorithm acquisition frequency.
