TAS3218 is an audio system-on-a-chip (SOC) designed for digital television audio systems and mini/micro
component applications. TAS3218 has a programmable audio DSP that preserves high-quality audio by using a
48-bit data path, 28-bit filter coefficients, and a single cycle 28 x 48-bit multiplier. The programmability feature
allows users to customize features in the DSP RAM.
The TAS3218 is composed of seven functional blocks.
Clock and serial data interface
Analog input and output
M8051 WARP controller, serial control interface, and device control
Audio DSP digital audio processing
