Requirement Description: Deep learning FPGA realizes knowledge reserveFrom: http://power.21ic.com/digi/technical/201603/46230.htmlWill the FPGA defeat the GPU and GPP and become the future of deep learning?In recent years, deep learning has become the most commonly used technology in computer vision, speech recognition, natural language processing and other key areas, which are of great concern to the industry. However, deep learning models require a very large amount of data and computing power
Shader and rendering pipelinesWhat is shaderShader, a Chinese translation, a shader, is a short program fragment that tells the graphics hardware how to calculate and output images, which were written in assembly language, and can now be written in high-level languages. In a nutshell: Shader is an algorithmic fragment of a programmable graphics pipeline.It is divided into two main categories: Vertex Shader and Fragment Shader.What is a rendering pipel
storage system becomes "virtual memory"Rom and RamRAM (random memory)Readable, writable, random access means that the time required to access any unit is the same, and when the power is lost, the contents of the store disappear immediately, known as volatileROM (read-only memory) Definition: Once the ROM has information, not easy to change, simple structure, so the density is higher than the read-write memory, with volatile Classification: Fixed mask model ROM (can no lo
spatial locality. I believe that everyone is familiar with the computer memory knowledge, here is not much to say, only simple mention.The main memory of GPU and CPU is realized by DRAM, and the cache is realized by using lower-latency SRAM. The storage structure of the GPU and CPU is basically the same. Moreover, CUDA presents the memory structure to the user better, thus allowing for more flexible control program behavior.CUDA Memory ModelFor programmers, memory can be divided into the follow
affect the system to work properly.There are different programmatic configuration methods for this:Parallel main mode for a piece of FPGA to add an EPROM way;Master-Slave mode can support a piece of prom programming multi-chip FPGA;Serial prom can be used to program FPGA.The peripheral mode allows the FPGA to be used as a peripheral to the microprocessor and programmed by the microprocessor.Identification and classification of 3.FPGA and CPLD:The device which constructs the logical behavior by
actually a pipeline. In fact, all the stages described earlier can be further decomposed into sub-processes. Figure 5: standard OpenGL and direct3d grating operations 5. Visualized graphic Assembly Line Figure 6 describes the stages of the graphic assembly line. In this figure, the two triangles are rasterized. The entire process begins with vertex transformation and coloring. Next, let's explain how to create a triangle from the vertex, as shown in the dotted line. Then, the gratin
Fault Analysis and Solution of Programmable switch, maintenance experience of JSQ-4000 type Programmable switch, JSQ-4000 is a type of digital time-controlled switch, using the distributed control mode, the number of users and relay of the port can be selected as needed and can be used as a user switch, a private network switch, or a C5 terminal switch.

greater than 18, an additional block of Ram will be occupied. The embedded multiplier module can implement an 18 × 18 or two 9 × 9 multiplier in a single module. The cyclone IV device I/O supports programmable bus persistence, programmable pull-up resistance, programmable latency, programmable drive capability, and
image processing field, it is also used for scientific computing, password cracking, numerical analysis, massive data processing (sorting, map-Reduce), financial analysis, and other fields that require large-scale parallel computing.Therefore, GPU can also be considered as a common chip.. FPGA came into being As people's computing needs become more and more professional, people hope that chips can better meet our professional needs. However, considering that hardware products cannot be changed
In a Linux system, when you enter a command, and then press two times the TAB key, all available commands that begin with the characters you enter are listed. It's not new, maybe you already know. This feature is called the command line complement bash completion. By default, the Bash command line can automatically complement the full file or directory name. However, we can enhance the Bash command complement function by complete command to reach a new height. This tutorial explains how we us
