  • lpc2478完全使用手册

    NXP Semiconductor designed the LPC2400 microcontrollers around a 16-bit/32-bitARM7TDMI-S CPU core with real-time debug interfaces that include both JTAG andembedded Trace. The LPC2400 microcontrollers have 512 kB of on-chip high-speedFlash memory. This Flash memory includes a special 128-bit wide memory interface andaccelerator architecture that enables the CPU to execute sequential instructions fromFlash memory at the maximum 72 MHz system clock rate. This feature is available onlyon the LPC2000 ARM Microcontroller family of products. The LPC2400 can execute both32-bit ARM and 16-bit Thumb instructions. Support for the two Instruction Sets meansEngineers can choose to optimize their application for either performance or code size atthe sub-routine level. When the core executes instructions in Thumb state it can reducecode size by more than 30 % with only a small loss in performance while executinginstructions in ARM state maximizes core performance.

  • PICKIT™ 2 PROGRAMMER-TO-

    PICKIT™ 2 PROGRAMMER-TO-GO USER GUIDE The PICkit 2 Programmer-To-Go functionality allows a PIC MCU memory image to be downloaded into the PICkit 2 unit for later programming into a specific PIC MCU. No software or PC is required to program devices once the PICkit 2 unit is set up for Programming-To-Go. A USB power source for the PICkit 2 is all that is needed.

  • Virtex-5, Spartan-DSP FPGAs Ap

    Virtex-5, Spartan-DSP FPGAs Application Note This application note demonstrates how efficient implementations of Digital Up Converters(DUC) and Digital Down Converters (DDC) can be done by leveraging the Xilinx DSP IPportfolio for increased productivity and reduced time to development. Step-by-step instruction is given on how to perform system-level trade off analysis and develop the most efficient FPGA implementation, thus allowing engineers a flexible, low-cost and low-power alternative to ASSP technologies.

  • Nios 的用户定义接口逻辑实例

    Nios 的用户定义接口逻辑实例 有许多人问我使用 Nios 的用户定义接口逻辑怎么用,想了几天决定设计一个实例来说明。该例为一个使用 user to interface logic 设计的 PWM 实例,其中包括三个文件:    plus32.v 是一个为 32bit nios 设计的 pwm 实例。    plus16.v 是一个为 16bit nios 设计的 pwm 实例。    test.s   是一个使用中断调用 pwm 的汇编语言测试程序。以上模块和程序均调试通过,并可稳定工作。这里让大家参考是使大家通过该例来真正理解 user to interface logic 设计方法,和nios 中通过汇编调用中断的方法,所以超值喔。另外热烈欢迎大家的指导。 注:在设计 Nios 时,将你调用的 user to interface logic 插件重命名为 plus_0,这样我的 test.s 可不作任何改动,你就可用示波器通过 nios 的 plus 管脚观察到一个要求的输出。

     1.The C Programming Language is a powerful, flexible andpotentially portable high-level programming language. 2.The C language may be used successfully to create a programfor an 8-bit MCU, but to produce the most efficient machinecode, the programmer must carefully construct the C Languageprogram.3.The programmer must not only create an efficient high leveldesign, but also pay attention to the detailed implementation.

  • 开放式汇编器系统的设计

    汇编器在微处理器的验证和应用中举足轻重,如何设计通用的汇编器一直是研究的热点之一。本文提出了一种开放式的汇编器系统设计思想,在汇编语言与机器语言间插入中间代码CMDL(code mapping description language)语言,打破汇编语言与机器语言的直接映射关系,由此建立起一套描述汇编语言与机器语言的开放式映射体系。基于此开放式映射体系开发了一套汇编器系统,具有较高层次上的通用性和可移植性。【关键词】指令集,CMDL,汇编器,开放式 Design of Retargetable Assembler System Liu Ling Feng Wen Nan Wang Ying Chun Jiang An Ping Ji Li Jiu IME of Peking University, 100871【摘要】An assembler plays a very important role in the field of microprocessor verifications and applications, thus how to build a retargetable assembler system has been a hotspot in this field for long time. This paper presents a new method about the retargetable assembler system design.It provides a kind of language CMDL, code mapping description language. During the process of assembling, assembler languages are firstly translated to CMDL, and then mapped to the machine codes. In an other word, CMDL is inserted between assembler languages and machine codes during the translation procedure. As a medium code, CMDL has a lot of features, such as high extraction, strong descript capabilities. It can describe almost all attributes of assembler languages. By breaking the direct mapping relationship between assembler languages and machine codes, the complexities of machine codes are hided to the users, therefore, the new retargetable assembler system has higher retargetable level by converting the mapping from assembler languages and machine codes to assembler languages and CMDL, and implementationof it becomes easier. Based on the new mapping system structure, a retargetable assemblersystem is developed. It proved the whole system has good retargetability and implantability.【关键词】instruction set, symbol table, assembler, lexical analysis, retargetability
