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

本應用指南講述一種實用的 MicroBlaze™ 系統(tǒng)，用于在非易失性 Platform Flash PROM 中存儲軟件代碼、用戶數(shù)據(jù)和配置數(shù)據(jù)，以簡化系統(tǒng)設(shè)計和降低成本。另外，本應用指南還介紹一種可移植的硬件設(shè)計、一個軟件設(shè)計以及在實現(xiàn)流程中使用的其他腳本實用工具。 簡介許多 FPGA 設(shè)計都集成了使用 MicroBlaze 和 PowerPC™ 處理器的軟件嵌入式系統(tǒng)，這些設(shè)計同時使用外部易失性存儲器來執(zhí)行軟件代碼。使用易失性存儲器的系統(tǒng)還必須包含一個非易失性器件，用來在斷電期間存儲軟件代碼。大多數(shù) FPGA 系統(tǒng)都在電路板上使用 Platform FlashPROM (在本文中稱作 PROM)，用于在上電時加載 FPGA 配置數(shù)據(jù)。另外，許多應用還可能使用其他非易失性器件(如 SPI Flash、Parallel Flash 或 PIC)來保存 MAC 地址等少量用戶數(shù)據(jù)，因此導致系統(tǒng)電路板上存在大量非易失性器件。

The data plane of the reference design consists of a configurable multi-channel XBERT modulethat generates and checks high-speed serial data transmitted and received by the MGTs. Eachchannel in the XBERT module consists of two MGTs (MGTA and MGTB), which physicallyoccupy one MGT tile in the Virtex-4 FPGA. Each MGT has its own pattern checker, but bothMGTs in a channel share the same pattern generator. Each channel can load a differentpattern. The MGT serial rate depends on the reference clock frequency and the internal PMAdivider settings. The reference design can be scaled anywhere from one channel (two MGTs)to twelve channels (twenty-four MGTs).

SPLASH is a c++ class library that implements many of the Perl constructs and data types, including extensive regex regular expression pattern matching. For those not familiar with Perl, it is an excellent scripting language by Larry Wall and is available for most platforms. This Class library provides List, String, Regular Expression, and text manipulation handling capabilities based on those provided in Perl
