Description

The TDA7590 is a high performances, fully

programmable 24-bit, 120 MIPS. Digital Signal

Processor (DSP), designed to support several

speech and audio applications, as Automatic

Speech Recognition, Speech Synthesis, MP3

Decoding, Echo and Noise Cancellation.

Nevertheless, the embedded CODECs bandwidth

and the generic processing engine allow to

proceed also full-band audio signals. The large

amount of on-chip memory (128 Kwords),

together with the 16 Mwords external memory

addressable and the 32 general purpose I/O pins

permit to build a DSP-system avoiding the usage

of an additional Microcontroller.

The presence of serial and parallel interfaces

allows easy connection with external devices

including CODECs, DSPs, Microprocessors and

Personal Computers.

In particular, the Debug/JTAG interface permits

the on-chip emulation of the firmware developed.

Further, the presence of the Timers and

Watchdog Block makes TDA7590 suitable for

PWM processing and allows the integration of a

system Watchdog.

Applications

Real time digital speech and audio processing:

speech recognition, speech synthesis, speech

compression, echo canceling, noise canceling,

MP3 decoding.
