PCB Layout Rule Rev1.70, 規(guī)範內容如附件所示, 其中分為: (1) ”PCB LAYOUT 基本規(guī)範”:為R&D Layout時必須遵守的事項, 否則SMT,DIP,裁板時無法生產. (2) “錫偷LAYOUT RULE建議規(guī)範”: 加適合的錫偷可降低短路及錫球. (3) “PCB LAYOUT 建議規(guī)範”:為製造單位為提高量產良率,建議R&D在design階段即加入PCB Layout. (4) ”零件選用建議規(guī)範”: Connector零件在未來應用逐漸廣泛, 又是SMT生產時是偏移及置件不良的主因,故製造希望R&D及採購在購買異形零件時能顧慮製造的需求, 提高自動置件的比例.

針對目前使用的RS232接口數(shù)字化B超鍵盤存在PC主機啟動時不能設置BIOS,提出一種PS2鍵盤的設計方法?;赪78E052D單片機,采用8通道串行A/D轉換器設計了8個TGC電位器信息采集電路,電位器位置信息以鍵盤掃描碼序列形式發(fā)送,正交編碼器信號通過XC9536XL轉換為單片機可接收的中斷信號,軟件接收到中斷信息后等效處理成按鍵。結果表明,在滿足開機可設置BIOS同時,又可實現(xiàn)超聲特有功能,不需要專門設計驅動程序,接口簡單,成本低。 Abstract: Aiming at the problem of the digital ultrasonic diagnostic imaging system keyboard with RS232 interface currently used couldn?蒺t set the BIOS when the PC boot, this paper proposed a design method of PS2 keyboards. Based on W78E052D microcontroller,designed eight TGC potentiometers information acquisition circuit with 8-channel serial A/D converter, potentiometer position information sent out with keyboard scan code sequentially.The control circuit based on XC9536 CPLD is used for converting the mechanical actions of the encoders into the signals that can be identified by the MCU, software received interrupt information and equivalently treatmented as key. The results show that the BIOS can be set to meet the boot, ultrasound specific functionality can be achieved at the same time, it does not require specially designed driver,the interface is simple and low cost.

The PCA9541 is a 2-to-1 I2C-bus master selector designed for high reliability dual masterI2C-bus applications where system operation is required, even when one master fails orthe controller card is removed for maintenance. The two masters (for example, primaryand back-up) are located on separate I2C-buses that connect to the same downstreamI2C-bus slave devices. I2C-bus commands are sent by either I2C-bus master and are usedto select one master at a time. Either master at any time can gain control of the slavedevices if the other master is disabled or removed from the system. The failed master isisolated from the system and will not affect communication between the on-line masterand the slave devices on the downstream I2C-bus.

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
