  • Introduction ? ? The ARM Cortex -A8 microprocessor is the first applications microprocessor in A

    Introduction ? ? The ARM Cortex -A8 microprocessor is the first applications microprocessor in ARM!ˉs new Cortex family. With high performance and power efficiency, it targets a wide variety of mobile and consumer applications including mobile phones, set-top boxes, gaming consoles and automotive navigation/entertainment systems. The Cortex-A8 processor spans a range of performance points depending on the implementation, delivering over to 2000 Dhrystone MIPS (DMIPS) of performance for demanding consumer applications and consuming less than 300mW for low-power mobile devices. This translates into a large increase in processing capability while staying with the power levels of previous generations of mobile devices. Consumer applications will benefit from the reduced heat dissipation and resulting lower packaging and integration costs.

  • 基于频率插值的4.0kbps 语音编码器的性能和设计(英文)

    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.

  • 高清版U-Boot 开发资料2020.

    高清版U-Boot 开发资料2020.Das U-Boot 是一个主要用于嵌入式系统的引导加载程序,可以支持多种不同的计算机系统结构,包括PPC、ARM、AVR32、MIPS、x86、68k、Nios与MicroBlaze。这也是一套在GNU通用公共许可证之下发布的自由软件。Das U-Boot可以在x86计算机上建构,但这部x86计算机必须安装有可支持特定平台结构的交互发展GNU工具链,例如crosstool、Embedded Linux Development Kit (ELDK)或OSELAS.Toolchain。U-Boot不仅仅支持嵌入式Linux系统的引导,它还支持NetBSD, VxWorks, QNX, RTEMS, ARTOS, LynxOS, android嵌入式操作系统。其目前要支持的目标操作系统是OpenBSD, NetBSD, FreeBSD,4.4BSD, Linux, SVR4, Esix, Solaris, Irix, SCO, Dell, NCR, VxWorks, LynxOS, pSOS, QNX, RTEMS, ARTOS, android。这是U-Boot中Universal的一层含义,另外一层含义则是U-Boot除了支持PowerPC系列的处理器外,还能支持MIPS、 x86、ARM、NIOS、XScale等诸多常用系列的处理器。这两个特点正是U-Boot项目的开发目标,即支持尽可能多的嵌入式处理器和嵌入式操作系统。就目前来看,U-Boot对PowerPC系列处理器支持最为丰富,对Linux的支持最完善。其它系列的处理器和操作系统基本是在2002年11 月PPCBOOT改名为U-Boot后逐步扩充的。从PPCBOOT向U-Boot的顺利过渡,很大程度上归功于U-Boot的维护人德国DENX软件工程中心Wolfgang Denk[以下简称W.D]本人精湛专业水平和执着不懈的努力。当前,U-Boot项目正在他的领军之下,众多有志于开放源码BOOT LOADER移植工作的嵌入式开发人员正如火如荼地将各个不同系列嵌入式处理器的移植工作不断展开和深入,以支持更多的嵌入式操作系统的装载与引导。
