Xilinx has won six performance champions of AIIa artificial intelligence end-to-side chip evaluation board

When it comes to FPGA, we have to mention two leading players: Xilinx and Altera. Which FPGA is better?

 Let's talk about the difference between xilinx distributor 's vivado IP generating globe and out of context per IP XC2V1000-4FG456I |  XCZU7EV-1FBVB900E |  XCZU7EG-1FBVB900E |  XCZU7EV-1FBVB900I |  XCZU7EG-1FBVB900E When using vivado of Xilinx to generate IP, there are two options: globe and out of context per IP, as shown in the following figure: So, which one to choose? 1 Globe -- IP generated files will be integrated with other user files 2: Out of context per IP -- out of context mode, which only needs to be synthesized once and generates. DCP (Design) When the project needs to use IP, you only need to parse the corresponding IP netlist file from the. DCP file, and do not need to re synthesize the IP. This way can speed up the integration. The gobal selection is that each time the project is integrated, the IP core will be integrated with the project, and the integration time is very long, and the. DCP file will not be generated. OOC also uses a constraint file that is use

 Let me talk about how FPGA can realize Gigabit Network UDP communication? The general steps are as follows: data to be transmitted -- "data of UDP protocol + data to be transmitted --" data of IP protocol + data of UDP protocol + data to be transmitted -- "data of preamble + data of MAC protocol + data of IP protocol + data of UDP protocol + data to be transmitted --" waveform that can be measured in RJ45 (as shown in the following picture like  fpgamall ) There are several types of MII between the data link layer and PHY: MII gmii rgmii srgmii. Which one should be paid attention to in use: In the hardware design, we need not pay attention xilinx distributor to much. Ethernet frame format: packets on the Ethernet link are called Ethernet frames. The Ethernet frame start part is composed of preamble and frame start character. It is followed by an Ethernet header, which indicates the destination address and the source address with the MAC address. In the middle of t

 South Korea's XCZU7EG-1FBVB900E dependence on Japan's semiconductors has increased instead of falling Although South Korea has been trying to reduce its dependence on Japan after Japan imposed export restrictions in July last year, its imports of semiconductor equipment from Japan are still about 80% higher than last year. sitemap On September 6, the Korea International Trade Association announced that in the first seven months of this year, South Korea imported 1.7 billion US dollars of semiconductor equipment and electronic integrated circuit manufacturing machinery from Japan, with a year-on-year increase of 77.2%. In addition, imports of processors and controllers and photosensitive semiconductor devices increased by 8.6% and 3.7% respectively. For reference, South Korea's total imports from Japan fell by about 10% over the same period last year. The increase in the import of semiconductor equipment is related to the large-scale investment of Samsung Electronics. EP1A
