This application note covers the design considerations of a system using the performance features of the LogiCORE™ IP Advanced eXtensible Interface (AXI) Interconnect core. The design focuses on high system throughput through the AXI Interconnect core with F MAX and area optimizations in certain portions of the design. The design uses five AXI video direct memory access (VDMA) engines to simultaneously move 10 streams (five transmit video streams and five receive video streams), each in 1920 x 1080p format, 60 Hz refresh rate, and up to 32 data bits per pixel. Each VDMA is driven from a video test pattern generator (TPG) with a video timing controller (VTC) block to set up the necessary video timing signals. Data read by each AXI VDMA is sent to a common on-screen display (OSD) core capable of multiplexing or overlaying multiple video streams to a single output video stream. The output of the OSD core drives the DVI video display interface on the board. Performance monitor blocks are added to capture performance data. All 10 video streams moved by the AXI VDMA blocks are buffered through a shared DDR3 SDRAM memory and are controlled by a MicroBlaze™ processor. The reference system is targeted for the Virtex-6 XC6VLX240TFF1156-1 FPGA on the Xilinx® ML605 Rev D evaluation board

The Xilinx Zynq-7000 Extensible Processing Platform (EPP) redefines the possibilities for embedded systems, giving system and software architects and developers a flexible platform to launch their new solutions and traditional ASIC and ASSP users an alternative that aligns with today’s programmable imperative. The new class of product elegantly combines an industrystandard ARMprocessor-based system with Xilinx 28nm programmable logic—in a single device. The processor boots first, prior to configuration of the programmable logic. This, along with a streamlined workflow, saves time and effort and lets software developers and hardware designers start development simultaneously.

在集成电路内建自测试的过程中,电路的测试功耗通常显著高于正常模式产生的功耗,因此低功耗内建自测试技术已成为当前的一个研究热点。为了减少被测电路内部节点的开关翻转活动率,研究了一种随机单输入跳变(Random Single Input Change,RSIC)测试向量生成器的设计方案,利用VHDL语言描述了内建自测试结构中的测试向量生成模块,进行了计算机模拟仿真并用FPGA(EP1C6Q240C8)加以硬件实现。实验结果证实了这种内建自测试原理电路的正确性和有效性。

Tug of War(A tug of war is to be arranged at the local office picnic. For the tug of war, the picnickers must be divided into two teams. Each person must be on one team or the other the number of people on the two teams must not differ by more than 1 the total weight of the people on each team should be as nearly equal as possible. The first line of input contains n the number of people at the picnic. n lines follow. The first line gives the weight of person 1 the second the weight of person 2 and so on. Each weight is an integer between 1 and 450. There are at most 100 people at the picnic. Your output will be a single line containing 2 numbers: the total weight of the people on one team, and the total weight of the people on the other team. If these numbers differ, give the lesser first. )

This simple simulation of a pulse traveling down a parallel-plate guide makes a handy test code for initial experiments with boundary conditions. ToyFDTD3 adds some simple features to ToyFDTD1: A PMC boundary condition, a sinusoidal pulse source, and output tracking a single point in the mesh. Released 15 June 1999.

PrintNow is a 32-bit application that runs only under Windows 95 or Windows NT 4.0. It allows your PrtScr and Alt+PrtScr keys to print a screen capture directly to your printer instead of just copying the image to the Windows clipboard. PrintNow can also print any DIB image in the clipboard, regardless of its original source. PrintNow supports multiple instances, it can print multiple copies of a screen capture to the same printer with different print settings, to several different printers, or any combination thereof, with a single keystroke.

Draak is a multi-language, macro compiler, meaning all syntax and code generation is defined in a single file. Draak is a single binary that is able to compile any context free language (like C, Pascal, Java) for any platform with only 1 file. Draak Compiler是一个多语言,宏编译器,可以在一个单独的文件中定义所有的语法和代码生成。Draak 是一个单独的二进制文件,可以在任意平台上只使用一个文件来编译任何上下文无关的语言(类似 C, Pascal, Java)。

The project KEIL_IODemo shows how to use memory allocation routines (malloc) and char I/O (printf, scanf) via a serial interface with the Keil ARM toolchain. The I/O functions are adapted for the Analog Devices ADuC7000 series using the SERIAL.C module. The example also shows the efficiency of the Keil CA ARM Compiler run-time library which is tuned for single chip systems.
