  • 便攜式超聲系統中的Xilinx器件

    There has long been a need for portable ultrasoundsystems that have good resolution at affordable costpoints. Portable systems enable healthcare providersto use ultrasound in remote locations such asdisaster zones, developing regions, and battlefields,where it was not previously practical to do so.

  • XAPP144 -設計CPLD多電壓系統

    Today’s digital systems combine a myriad of chips with different voltage configurations.Designers must interface 2.5V processors with 3.3V memories—both RAM and ROM—as wellas 5V buses and multiple peripheral chips. Each chip has specific power supply needs. CPLDsare ideal for handling the multi-voltage interfacing, but do require forethought to ensure correctoperation.

  • XAPP328-使用CPLD設計MP3播放器

      MP3 portable players are the trend in music-listening technology. These players do not includeany mechanical movements, thereby making them ideal for listening to music during any type ofactivity. MP3 is a digital compression technique based on MPEG Layer 3 which stores music ina lot less space than current CD technology. Software is readily available to create MP3 filesfrom an existing CD, and the user can then download these files into a portable MP3 player tobe enjoyed in almost any environment.

  • XAPP708 -133MHz PCI-X到128MB DDR小型DIMM存儲器橋

      The Virtex-4 features, such as the programmable IDELAY and built-in FIFO support, simplifythe bridging of a high-speed, PCI-X core to large amounts of DDR-SDRAM memory. Onechallenge is meeting the PCI-X target initial latency specification. PCI-X Protocol Addendum tothe PCI Local Bus Specification Revision 2.0a ([Ref 6]) dictates that when a target signals adata transfer, "the target must do so within 16 clocks of the assertion of FRAME#." PCItermination transactions, such as Split Response/Complete, are commonly used to meet thelatency specifications. This method adds complexity to the design, as well as additional systemlatency. Another solution is to increase the ratio of the memory frequency to the PCI-X busfrequency. However, this solution increases the required power and clock resource usage.

  • Verilog編碼中的非阻塞性賦值

      One of the most misunderstood constructs in the Verilog language is the nonblockingassignment. Even very experienced Verilog designers do not fully understand how nonblockingassignments are scheduled in an IEEE compliant Verilog simulator and do not understand whenand why nonblocking assignments should be used. This paper details how Verilog blocking andnonblocking assignments are scheduled, gives important coding guidelines to infer correctsynthesizable logic and details coding styles to avoid Verilog simulation race conditions

  • CPLD和FPGA設計介紹

    Field Programmable Gate Arrays (FPGAs) are becoming a critical part of every system design. Many vendors offer many different architectures and processes. Which one is right for your design? How do you design one of these so that it works correctly and functions as you expect in your entire system? These are the questions that this paper sets out to answer.

  • UART 4 UART參考設計,Xilinx提供VHDL代碼

    UART 4 UART參考設計,Xilinx提供VHDL代碼 uart_vhdl This zip file contains the following folders:  \vhdl_source  -- Source VHDL files:      uart.vhd  - top level file      txmit.vhd - transmit portion of uart      rcvr.vhd -  - receive portion of uart \vhdl_testfixture  -- VHDL Testbench files. This files only include the testbench behavior, they         do not instantiate the DUT. This can easily be done in a top-level VHDL          file or a schematic. This folder contains the following files:      txmit_tb.vhd  -- Test bench for txmit.vhd.      rcvr_tf.vhd  -- Test bench for rcvr.vhd.
