TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC9331F
Audio Digital Signal Processor
The TC9331F digital integrated circuit facilitates real time
processing of digital signals in audio equipment for digital filters
such as equalizers, dynamic range controllers for compressors
and expanders, as well as acoustic field simulators that produce
concert hall effects. The TC9331F is a-high speed, high-definition
audio digital processor.
Features
The TC9331F features a 32 bit main bus.
The TC9331F is capable of both reading from and writing to
external sources of RAM data and allows for the simultaneous
accumulation, operation, and integration of the data that
needs to be processed.
Multiplier/adder: 32 bit × 16 bit + 51 bit → 51 bit
Shifter: +4, +1 bit shift
Accumulator: 51 bit (code extension 4 bit)
Work register: 2 registers (32 and 47 bit)
Program RAM: 320 words × 32 bit
Data RAM: 128 words × 32 bit (Mode 1)
(128 words × 16 bit) × 2 (Mode 2)
Coefficient RAM: 320 words × 16 bit
Offset address RAM: 64 words × 16 bit
The interface parameters for external RAM sources are as follows
Data word length: Both 16 bit and 32 bit
External RAM: 1 M DRAM, 256 K DRAM, 256 K pseudo-static RAM (PSRAM)
The following five ports have been made available for use as serial data ports.
Serial data input ports: 2 ports (SDI0, SDI1)
Serial data output ports: 3 ports (SDO0, SDO1, SDO2)
Data word length: Both 16 and 32 bit
Data format: 2's complement, MSB first
The program's settings, coefficient data, and offset data can be made converted through the microprocessor
interface.
The CMOS construction of the TC9331F makes high-speed processing possible.
The TC9331F features a flat, 80 pin package design.
Weight: 1.57 g (typ.)
