DESCRIPTION
The TDA755X family is a high performances, fully
programmable 24-bit, 50 MIPS Digital Signal
Processor (DSP), designed to support several
speech and audio applications, as Automatic
Speech Recognition, Speech Synthesis, Speaker
Verification, Echo and Noise Cancellation. Soft-
ware for these applications is licenced by Lernout
& Hauspie and NCTI.
It offers an effective solution for this kind of appli-
cations because of the A/D and D/A converters
and the big amount of memory integrated on chip.
This is preliminary information on a new product now in development. Details are subject to change without notice.
