DSP（DIGITAL singnal processor）是一种独特的微处理器，是以数字信号来处理大量信息的器件。其工作原理是接收模拟信号，转换为0或1的数字信号，再对数字信号进行修改、删除、强化，并在其他系统芯片中把数字数据解译回模拟数据或实际环境格式。它不仅具有可编程性，而且其实时运行速度可达每秒数以千万条复杂指令程序，源源超过通用微处理器，是数字化电子世界中日益重要的电脑芯片。它的强大数据处理能力和高运行速度，是最值得称道的两大特色

The TAS3204 is a highly-integrated audio system-on-chip (SOC) consisting of a fully-programmable, 48-bit DIGITAL audio processor, a 3:1 stereo analog input MUX, four ADCs, four DACs, and other analog functionality. The TAS3204 is programmable with the graphical PurePath Studio™ suite of DSP code development software. PurePath Studio is a highly intuitive, drag-and-drop environment that minimizes software development effort while allowing the end user to utilize the power and flexibility of the TAS3204’s DIGITAL audio processing core. TAS3204 processing capability includes speaker equalization and crossover, volume/bass/treble control, signal mixing/MUXing/splitting, delay compensation, dynamic range compression, and many other basic audio functions. Audio functions such as matrix decoding, stereo widening, surround sound virtualization and psychoacoustic bass boost are also available with either third-party or TI royalty-free algorithms. The TAS3204 contains a custom-designed, fully-programmable 135-MHz, 48-bit DIGITAL audio processor. A 76-bit accumulator ensures that the high precision necessary for quality DIGITAL audio is maintained during arithmetic operations. Four differential 102 dB DNR ADCs and four differential 105 dB DNR DACs ensure that high quality audio is maintained through the whole signal chain as well as increasing robustness against noise sources such as TDMA interference. The TAS3204 is composed of eight functional blocks: Clocking System DIGITAL Audio Interface Analog Audio Interface Power supply Clocks, DIGITAL PLL I2C control interface 8051 MCUcontroller Audio DSP – DIGITAL audio processing 特性 DIGITAL Audio Processor Fully Programmable With the Graphical, Drag-and-Drop PurePath Studio™ Software Development Environment 135-MHz Operation 48-Bit Data Path With 76-Bit Accumulator Hardware Single-Cycle Multiplier (28 × 48)
