Description
The SC-601 is a low-cost, mixed-signal
processor that combines a speech synthesizer,
general-I/O, onboard ROM, and direct speaker
drive in a single package. The computational
unit utilizes a powerful DSP which gives the SC-
601 unprecedented speed and computational
flexibility compared with previous devices of its
type. The SC-601 supports a variety of speech
and audio coding algorithms, providing range of
options for speech duration and sound quality.
The device consists of a micro-DSP core,
embedded program, and data memory, and a
self-contained generation system. General-
purpose periphery is comprised of 32 bits of partially configurable I/O.
The core processor is a general-purpose 16-bit microcontroller with DSP capability. The basic core 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-601 break-capability in emulation.
The processor is Harvard type for efficient DSP algorithm execution. It requires separate program and memory
blocks to permit simultaneous access. The ROM has a protection scheme to prevent third-party pirating. It is
configured in 32K 17-bit words.
The total ROM space is divided into three areas:
1. The lower 2K words are reserved by Sensory a built-in self-test
2. The upper 30K words are for user program/data
3. An additional 1 Mb data ROM provides for up to 24 minutes of speech.
