Description
The SC-614 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 SC-614 unprecedented speed and
computational flexibility compared with previous devices
of its type. The SC-614 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 microcontroller 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 SC-614 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 Sensory for the purposes of a built-in self-test
2. The upper 30K is for user program/data
