The VoiceDSP™ product family combines multi-
ple digital signal processing functions on a single
chip for cost-effective solutions in telephony, au-
tomotive and consumer applications.
The VoiceDSP processor offers necessary fea-
tures to modern telephony products, such as:
high-quality, speech record and playback, elec-
trical and acoustic echo cancellation for full-du-
plex hands-free speakerphone operation.

VoiceDSP™ Digital Speech Processor with
Preliminary Information
—Advance Information—
Based on ISD’s unique concept which combines
16-bit DSP (Digital Speech Processor) and 16-bit
RISC core technology, the ISD-T360SB is a high-
performing chip solution for various applications.
To facilitate incorporating the VoiceDSP proces-
sor, it features system support functions such as
an interrupt control unit, codec interface (mas-
ter, slave), Microwire interface to the system mi-
crocontroller, as well as a memory handler for
Flash and DRAM memory devices. Design of
high-end, price optimized systems are possible
with ISD’s VoiceDSP flexible system interfaces
(codec, microcontroller, and memory manage-
ment support).
The ISD-T360SB processor operates as a peripher-
al controlled by the system microcontroller via
an enhanced, serial Microwire interface. The sys-
tem microcontroller typically controls the analog
circuits, buttons and display, as well as activates
functions through commands. The VoiceDSP ex-
ecutes these commands and returns status infor-
mation to the Microcontroller.
The VoiceDSP software resides in the on-chip
ROM. It includes DSP-based algorithms, system
support functions, and a software interface to
hardware peripherals.
