ARM架构,过去称作高级精简指令集机器(Advanced RISC Machine,更早称作:Acorn RISC Machine),是一个32位精简指令集reduced instruction set computing(RISC)处理器架构,其广泛地使用在许多嵌入式系统设计。由于节能的特点,ARM处理器非常适用于移动通信领域,符合其主要设计目标为低成本、高性能、低耗电的特性。
The most unique aspect of the system is its multicore processing node which integrates six MIPS64 cores, a crossbar memory controller, interconnect DMA engine, Gigabit Ethernet and PCI Express controllers all on a single chip which consumes only 10 watts of power, yet has a peak floating ...
与ARM 和 MIPS 最大的差别还是在于其为 RISC-V 基金会进行标准的制定和维护工作而非商业公司,任何人可以无偿使用该指令集开发自己的 CPU ,或者往自己已有的芯片中集成开源免费的 RISC-V IP Core,这是比较吸引电子设备厂商的重要原因。 PS:之前的内容更多关注在 RISC-V,忽视了题目本身是比较 ARM,MIPS 和 RISC...
设计人员可通过CorExtend为内核增加功能,在目标应用中对成为瓶颈的特定应用功能进行加速,从而提高系统的整体性能。在典型MCU环境中,CorExtend可用于设计专用图形控制器、TCP/IP加速器、定制安全/加密逻辑、无线基带控制或其他实时控制接口等。CorExtend与内核流水线协同工作,如图3所示。CorExtend的功能与MIPS32完全兼容,...
