FPGA Image Processing-pip Introduction to the hardware structure and software: FPGA, arria ii gx series chip. Altera Development Board, http://www.altera.com.cn/products/devkits/altera/kit-aiigx-pcie.htmlmy Development Kit information. Two important information: FPGA: EP2AGX125EF35. DDR2: 1G, 64-bit. It runs at 200 MB. The input value is 1080 P, that is, 1920*1080. Each of the 8 bits in RGB format has a tot

P2P users, set it by yourself. Extended Life Cycle of SSDThe x300 has already used SSD. In the long run, SSD is still the same as ephemeral SSD, but the number of ephemeral SSD cannot be as complex as that of the hard disk, place memory and Memory on ramdisk to reduce the complexity of SSD storage and prolong the lifetime of SSD storage. ConclusionHow to use a memory is different. If a large amount of memory is spent, the memory is useless. It is also a kind of waste. In addition to some mem

-Gates is used by enterprises to solve the problem of producing vertical hardware models, c2h is written in different ways, it uses the production assistant to unload and increase the processing efficiency of the processing tool on the microprocessor using the C language, this method can solve an important issue: 1. similar to the prototype of the computation that really accelerates the computation, or the C statement that has been written on a common micro-processor, or, the digital processin

ObjectiveModelsim is a professional simulation software, especially in the version after the Quartus II 11.0, there is no matching their own simulation software, so modelsim into the FPGA design process for the simulation of the first choice of software.???? Modelsim is a HDL simulation tool that we can use to implement the VHDL or Verilog designSupport the various hardware description Language standards common to IEEE. You can do mixed simulations in two languages, but it is recommended that yo

, the PLD/FPGA development software automatically calculates all possible results of the logic circuit and writes the truth table (that is, the result) to ram beforehand, so that each input signal is logically calculated to be equal to the input of an address to look up the list, Find out what the address corresponds to and then output it.Table 2-1 input and door truth tablesAs you can see from the table, the LUT has the same functionality as the logic circuitry. In fact, the LUT has a faster ex

referred to as Vccint) is used to give the logic gate and the voltage on the trigger inside the FPGA. The voltage increases with the development of FPGA from 5v, 3.3v, 2.5v, 1.8v, 1.5v and lower. The core voltage is fixed. (determined based on the mode of the FPGA used). The IO voltage (Vccio) is the voltage on the IO module (the same IO pin) used for the FPGA. This voltage should match the voltage of other devices connected to the FPGA.In fact, the FPGA device itself allows Vccint and Vccio to

FPGA selection problem under targeted arrangementFirst, access to chip information:To do the selection of the chip, the first is to have the potential to face the chip has a holistic understanding, that is, as much as possible first to obtain the information of the chip. Now there are 4 main FPGA manufacturers, Altera,xilinx,lattice and Actel. The most convenient way to get information is the official website of these manufacturers (http://www.altera.

Porting uClinux to NIOSII under Fedora9-general Linux technology-Linux programming and kernel information. The following is a detailed description. To participate in the competition, we need to use the operating system uClinux in our solution. The Development Board is the DE1 Board provided by Altera. Porting uClinux is an essential step. We have been familiar with this system before, but I have never transplanted it myself. The first step is to use

differential signal over the transmission line. Here there is a process of numerical simulation, this is not what FPGA can do. The above two problems are not only encountered when implementing the SATA protocol, but also many high-speed serial transmission protocols, such as PCIe, used for FPGA implementation. FPGA vendors generally integrate dedicated hardware into FPGA chips to support this high-speed serial transmission protocol, this kind of dedicated hardware is usually a set of serializer

following different methods of synthesis. 　　1.2.1 to reduce delay by changing the way the line goes Take the Altera device as an example, we can see a lot of floorplan in the timing closure She in Quartus, we can divide the She by row and by column, each bar represents 1 lab, 8 in each lab or 10 le. The relationship of their line-delay is as follows: the same lab (fastest) 　　1.2.2 to reduce delay by splitting the combinatorial logic As the general

U-boot Analysis Two Following the previous launch, this blog post aims to: Learn the U-boot directory structure, from the code architecture on the U-boot have a overall grasp and understanding. First, learn u-boot, ask, what is U-boot? U-boot is an open source program. Universal boot Loader, Universal boot program. is a very common boot program that can be used as a mainstream system bootstrapper, such as OpenBSD, NetBSD, Freebsd,4.4bsd, Linux, SVR4, Esix, Solaris, and so on, while also support

First, the FPGA can do two types of chips, digital circuits and microprocessors Microprocessors generally and SOPC on-chip systems (that is, the microprocessor and some on-chip peripherals are integrated into a chip) to do together, such as Nios-ii, and then again Digital circuits are divided into: Combinational logic circuits (circuits of various and/or non-gates, output depends only on current input), e.g. compiler code, adder Sequential logic circu

-port microcontroller, and "UART Controller" is another term of SCI) Many commonly used chips contain SCI, for example, the arm's S3C2410X chip is embedded with three serial interface controllers, while the soft-core chips such as NIOS can use the UART (RS232) IP address to control UART. PC usually uses 16650 UART, 16750 uart and other control serial ports. If you implement a software UART, it takes a lot of time for the UART to check the serial acti
