Description

SC-614 Block Diagram

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
