PowerPC

PowerPC(英語(yǔ):PerformanceOptimizationWithEnhancedRISC–PerformanceComputing,有時(shí)簡(jiǎn)稱PPC)是一種精簡(jiǎn)指令集(RISC)架構(gòu)的中央處理器(CPU),其基本的設(shè)計(jì)源自IBM的POWER(PerformanceOptimizedWithEnhancedRISC;《IBMConnect電子報(bào)》2007年8月號(hào)譯為“增強(qiáng)RISC性能優(yōu)化”)架構(gòu)。POWER是1991年,Apple、IBM、Motorola組成的AIM聯(lián)盟所發(fā)展出的微處理器架構(gòu)。PowerPC是整個(gè)AIM聯(lián)盟平臺(tái)的一部分,并且是唯一的一部分。但蘋(píng)果電腦自2005年起,將旗下電腦產(chǎn)品轉(zhuǎn)用IntelCPU。

  • XAPP806 -決定DDR反饋時(shí)鐘的最佳DCM相移

    This application note describes how to build a system that can be used for determining theoptimal phase shift for a Double Data Rate (DDR) memory feedback clock. In this system, theDDR memory is controlled by a controller that attaches to either the OPB or PLB and is used inan embedded microprocessor application. This reference system also uses a DCM that isconfigured so that the phase of its output clock can be changed while the system is running anda GPIO core that controls that phase shift. The GPIO output is controlled by a softwareapplication that can be run on a PowerPC® 405 or Microblaze™ microprocessor.

  • XAPP719 -利用USR_ACCESS寄存器實(shí)現(xiàn)PowerPC高速緩存配置

    The Virtex™-4 user access register (USR_ACCESS_VIRTEX4) is a 32-bit register thatprovides direct access to bitstream data by the FPGA fabric. It is useful for loadingPowerPC™ 405 (PPC405) processor caches and/or other data into the FPGA after the FPGAhas been configured, thus achieving partial reconfiguration. The USR_ACCESS_VIRTEX4register is programmed through the bitstream with a command that writes a series of 32-bitwords.

  • XAPP807-封裝最小的三態(tài)以太網(wǎng)MAC處理引擎

    The Tri-Mode Ethernet MAC (TEMAC) UltraController-II module is a minimal footprint,embedded network processing engine based on the PowerPC™ 405 (PPC405) processor coreand the TEMAC core embedded within a Virtex™-4 FX Platform FPGA. The TEMACUltraController-II module connects to an external PHY through Gigabit Media IndependentInterface (GMII) and Management Data Input/Output (MDIO) interfaces and supports tri-mode(10/100/1000 Mb/s) Ethernet. Software running from the processor cache reads and writesthrough an On-Chip Memory (OCM) interface to two FIFOs that act as buffers between thedifferent clock domains of the PPC405 OCM and the TEMAC.

    The use of the Wind River VxWorks Real-Time Operating System (RTOS) on Virtex™-4embedded PowerPC™ processors continues to be a popular choice for high performanceFPGA designs. The introduction of the Wind River Workbench design environment has enableda new and easier way for designers to control the configuration of the VxWorks kernel. Thisguide shows the steps required to build and configure a ML403 Embedded DevelopmentPlatform to boot and run the VxWorks RTOS. A VxWorks bootloader is created, programmedinto Flash, and used to boot the design. The concepts presented here can be scaled to anyPowerPC enabled development platform.
