TDA7590：Digital signal processing IC for speech and audio applications
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.
