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.
TQFP144
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.
