The VoiceDSP™ product family combines multiple

digital signal processing functions on a single chip

for cost-effective solutions in telephony, automo-

tive and consumer applications.

The VoiceDSP processor offers necessary features

to modern telephony products, such as: high-

quality speech record and playback, electrical

and acoustic echo cancellation for full-duplex

hands-free speakerphone operation.

The T360SB VoiceDSP can be used in various ap-

plications:

•

Full-Duplex Speakerphone, Master/Slave CODEC Interface and

VoiceDSP

—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 (master,

slave), Microwire interface to the system micro-

controller, as well as a memory handler for Flash

memory devices. Design of high-end, price opti-

mized systems are possible with ISD’s VoiceDSP

flexible system interfaces (codec, microcontroller,

and memory management support).

The ISD-T360SB processor operates as a peripheral

controlled by the system microcontroller via an

enhanced, serial Microwire interface. The system

microcontroller typically controls the analog cir-

cuits, buttons and display, as well as activates

functions through commands. The VoiceDSP exe-

cutes 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.
