order. Rom is produced on the production line. Due to the high cost, it is generally used only in mass applications. Prom Programmable read-only memory can only be written once. If it is wrong, it has to be decommissioned. Now it is seldom used. It seems that the memory is used in the OPT single-chip microcomputer with lower costs.

network that uses cell technology to achieve a fixed field strength. It is a one-way communication system for internal use within the building. The system consists of a wireless paging control center, a micro-cell transmitting unit, a data transmission line, and a paging receiver. The paging Control Center is located on the underground floor of the hotel. It is connected to the hotel's programmable telephone switch to enable the switch extension pagi

Siganl In0 ~ The Siganl In3 corresponds to the echo signals of the four-way probe respectively, and the Signal Out is the echo Signal after buffer driving and Impedance Transformation. The P0 port of the single-chip microcomputer provides two signal lines for the MAX4141 channel selection. Table 1 shows the specific work conditions. 4 high frequency ampl

controllers: 1. Programmable Interrupt Controller 8259A Traditional PIC (Programmable Interrupt ControllerTwo 8259A external chips are connected in cascade mode. Each chip can process up to 8 different IRQ. Since the INT output line of the PIC is connected to the IRQ2 pin of the main PIC, the number of available IRQ lines reaches 15, as shown in 1.Figure 1: 8259A cascade schematic 2. Advanced

interrupt priority, and higher-priority interruptions may occur. This means that the first-level interrupt processing code must be carefully written, and the interrupt processing process should have its own stack, this allows you to store the CPU execution status (General registers and context of all CPUs) before the process is interrupted ). Some CPUs have a set of special registers-they exist only in the interrupt mode and can be used in the interrupt mode to save the execution context requir

only after a command is aborted. Asynchronous interruption (usually from the outside) refers to the interruption signal randomly generated by other hardware devices according to the CPU clock. In Intel 80x86 CPU manual, synchronous and asynchronous interrupts are also called "exception" and "interrupt" respectively )".PS: it can be understood that interrupt in the narrow sense is actually an asynchronous interrupt, while interrupt in the broad sense also includes exception (Exceptions include f

The Digital Temperature and Humidity Sensor sht15 is used to form a temperature and humidity detection circuit, and the result is displayed on the LED or LCD. 1-18 the design of a 4-channel output programmable current source based on max525.

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

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
