DMA20001X提供了比IS95B更为丰富的数据业务，SCH数据速率可以从9.6kpbs到153.6kbps不等。吞吐量是衡量数据业务性能优劣的重要指标之一，对于网络的每一层（物理层、SDU层、mux层、RLP层、PPP层、TCP/IP层、应用层）都有相应的吞吐量，虽然在物理层能够提供最大数据业务吞吐量为153.6+9.6＝163.2kpbs，但是由于层间复用，在数据包中增加了数据头，使得经过多层复用以后数据包长度变长；另外由于采用了RLP重传机制，以及RLP层应答延时的引入，使得一个终端用户实际感受到的有效吞吐量要小得多。 本文分析了各层复用所引入的信息冗余，以及由于误码导致重传而引起的有效吞吐量的降低，通过计算，定量分析，为CDMA20001X数据业务吞吐量的优化提供了理论依据

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)
