Enhanced version of the Serial Peripheral Interface available on Motorola s MC68HC11 family of CPUS.Enhancements include a wider supported operating frequency range, 4deep read and write fifos, and programmable transfer count dependent interrupt generation. As with the SPI found in MC68HC11 processors the core features programmable clock phase [CPHA] and clock polarity [CPOL]. The core features an 8bit wishbone interface. Very simple, very small.

SL811开发资料_包含源程序_电路图_芯片资料:SL811HS Embedded USB Host/Slave Controller.The SL811HS is an Embedded USB Host/Slave Controller capable of communicate with either full-speed or low-speed USB peripherals. The SL811HS can interface to devices such as microprocessors, microcontrollers, DSPs, or directly to a variety of buses such as ISA, PCMCIA, and others. The SL811HS USB Host Controller conforms to USB Specification 1.1.The SL811HS USB Host/Slave Controller incorporates USB Serial Interface functionality along with internal full-/low-speed transceivers.The SL811HS supports and operates in USB full-speed mode at 12 Mbps, or at low-speed 1.5-Mbps mode.The SL811HS data port and microprocessor interface provide an 8-bit data path I/O or DMA bidirectional, with interrupt support to allow easy interface to standard microprocessors or microcontrollers such as Motorola or Intel CPUS and many others. Internally,the SL811HS contains a 256-byte RAM data buffer which is used for control registers and data buffer.The available package types offered are a 28-pin PLCC (SL811HS) and a 48-pin TQFP package (SL811HST-AC). Both packages operate at 3.3 VDC. The I/O interface logic is 5V-tolerant.

This document constitutes the user manual for the YAMON™ ROM monitor. YAMON (“Yet Another MONitor”) is the ROM monitor used on MIPS Technologies evaluation and reference boards. The target audience for this document is users of those boards. This would typically be engineers developing hardware or software including compilers, RTOS and other tools. Currently, the following boards/CPUS are supported by YAMON : • Atlas™ with MIPS32 4K™ or MIPS64 5K™ class of CPUS. • Atlas with QED RM5261® . • Malta™ with MIPS32 4K or MIPS64 5K class of CPUS. • Malta with QED RM5261® . • SEAD™ with MIPS32 4K or MIPS64 5K class of CPUS. • SEAD-2™ with MIPS32 4K or MIPS64 5K class of CPUS.

The purpose of this project is to explore the issues and implementation of a multiple instruction stream, single data stream processor. We are running two instruction streams on two CPUS which share an address space. The processors share a second level cache, and maintain coherence at the L1 cache with a write-invalidate policy. The L2 cache is two-way set associative, with a block size of 8 words, and a total capacity of 512 words.

首先下载软件，解压软件，安装在程序中找到SEGGER,选里面的J-FLASH，进入界面，刚开始的那个界面可以忽略，不用建project也可以；单击菜单栏的“Options---Project settings”打开设置，进行jlink配置;正在General选项，选择“USB”，一般都是默认配置，确认一下即可;然后在CPU选项，选择芯片型号，先选择“Device”才能选择芯片型号，芯片型号，要根据你使用的芯片进行选择;在Target interface选项 里面选择SWD模式;首先Target里面选“Connection”连接目标芯片，然后 Target--Auto进行程序烧写;首先Target里面选择“Connection”连接目标芯片，然后 Target--Auto进行程序烧写.SEGGER J-Links are the most widely used line of debug probes available today. They've proven their value for more than 10 years in embedded development. This popularity stems from the unparalleled performance, extensive feature set, large number of supported CPUS, and compatibility with all popular development environments.
