ArticleDirectory Clock offset I. Area Structure Design 1. the folding assembly line can optimize the area of the assembly line design for the pipeline-level replication logic. The method of "folding Pipeline" is the opposite of "disassembling the loop", and is an area and speed interchange method. 2. shared logical resources sometimes require dedicated control circuits to determine which components are input to a specific structure. In some applications, resource input is often m

This network to multi-port module can easily realize the data transparent transmission between network equipment and multiple serial devices.This scheme is based on fpga+w5500. The serial port part uses the serial data to send and receive the hardware accelerator, make full use of the buff and FIFO resources, and greatly improve the data scheduling ability of 16 serial port. At the same time, the network part uses Toe technology's W5500, thus greatly

Application Specific intergrated circuits (ASIC) is an integrated circuit designed and manufactured according to the requirements of specific users and specific electronic systems. FPGA, short for field programmable gate array, is a field programmable gate array. It is a product of further development on the basis of PAL, gal, PLD and other programmable devices. As a semi-customized circuit in the specialized Integrated Circuit (ASIC) field, it not

Most FPGA developers are accustomed to graphical interfaces (GUIs). The GUI approach is easy to learn and provides a one-click process for small projects. However, as FPGA projects become more complex, in many cases GUI tools hinder productivity. Because GUI tools do not provide sufficient flexibility and control over the entire development process. On the other side, the GUI tool itself consumes a large am

The implementation of the Arduino and FPGA interaction, of course, there is no new protocol, or based on serial communication, now learn a serial communication can basically drive most modules, and with a variety of single-chip computer seamless data interaction, Arduino because of its powerful library function support, in the implementation of many things will be convenient many , such as serial communication, Arduino on two lines of code, Verilog at

How do they compare their capacity? "Of course, most of the time, when I design for the customer, I will use the highest capacity products directly, because our products are not sensitive to cost. However, this is still a comparis

1 compared with ASIC, FPGA is a power-consuming device and is not suitable for designing ultra-low power consumption.2 in CMOS technology, the dynamic power consumption of the circuit is related to the charge and discharge of the gate and the metal lead. The general equation of capacitor current consumption isI = V * C * FV is the voltage, which is a fixed value for FPGA. The C capacitor is related to the n
