ATmage32 + microchip的enc28j60实现web server的解决方案,比lpc2132之类的arm7方案可靠,但是性能会低,如果用在数据处理量很小的领域,AVR的芯片比LPC ARM7的要稳定。压缩包有源代码和电路板原理图,因为AVR单片机不限简单,没必要提供PCB,需要的朋友看一下压缩包里面PDF格式的PCB图就可以参考各种外围器件的选用了。

LPCARM2400开发平台配套的GPRS的程序,是ADS的,里面有详细的使用说明和注释,编译无误。LPC24XX的资料很难找的尤其是ZLG的,贡献一下了。

这个是比较详尽的飞利浦lpc22xx系列的资料,相对于lpc其他较少的资料而言,这个pdf还是比较全面的!

ucos 在smartarm2200上的移植,这里没有采用ZLG的移植方法,而是采用ucos官方的方法重新进行的移植

The 4.0 kbit/s speech codec described in this paper is based on a Frequency Domain Interpolative (FDI) coding technique, which belongs to the class of prototype waveform Interpolation (PWI) coding techniques. The codec also has an integrated voice activity detector (VAD) and a noise reduction capability. The input signal is subjected to LPC analysis and the prediction residual is separated into a slowly evolving waveform (SEW) and a rapidly evolving waveform (REW) components. The SEW magnitude component is quantized using a hierarchical predictive vector quantization approach. The REW magnitude is quantized using a gain and a sub-band based shape. SEW and REW phases are derived at the decoder using a phase model, based on a transmitted measure of voice periodicity. The spectral (LSP) parameters are quantized using a combination of scalar and vector quantizers. The 4.0 kbits/s coder has an algorithmic delay of 60 ms and an estimated floating point complexity of 21.5 MIPS. The performance of this coder has been evaluated using in-house MOS tests under various conditions such as background noise. channel errors, self-tandem. and DTX mode of operation, and has been shown to be statistically equivalent to ITU-T (3.729 8 kbps codec across all conditions tested.
