Recently just need to do page analysis, before all with Anyevent::http and Web::scraper. This time tried mojo::D om and mojo::useragent.First of all, my trial conclusion is: If the program is not with the web, just a page analysis or file processing program, it is good. Otherwise, you can consider mojo.First say Mojo: The advantages of:D om and

Many of the friends who have done microcontroller know that after the MCU is burned to write the program firmware, then the program firmware is stored inside the MCU. The program can continue to operate even if the MCU is powered off and then re-energized. This is because the firmware of the MCU is written to write the program firmware to the MCU on-chip program memory ROM, and most modern MCU this ROM is flash memory. Flash memory can be power-down to keep data, so can realize the power-down pr
DDR2 Circuit DesignHigh-speed large-capacity cache is an essential hardware in high-speed big data applications. At present, the use of a wide range of high-speed large-capacity memory in FPGA system has a classical low-speed single data rate of SDRAM memory, and high-speed dual-rate DDR, DDR2, DDR3 type SDRAM memory, The DDR series of memory all require the FPGA chip has the corresponding hardware circuit
FPGA timing problems and fpga timing problems
Recently I made a project ------ 4 1080 p (1920x1080) to synthesize a 4 K (3840x2160,297 M) interface board. When 1080 p goes in and p goes out, the video is played normally. However, when P and 4 K are in progress, the video image will have water ripple. At that time, it was assumed that the timing sequence sent by FPGA
The advanced embedded market is divided into the following three categories: ARM, DSP and FPGA. ARM is the industry leader, currently almost all Android smartphones use ARM authorized CPU architecture, while DSP (digital signal processor) has been widely used in the early years of the telephone, DVD, communication base Station and other fields. The difference between DSP and arm is that arm is a universal CPU,DSP and a dedicated CPU.
Implementation of floating-point operations in FPGA-calibration and fpga floating-point operations
In some FPGAs, floating point numbers cannot be operated directly, but only fixed points can be used for numerical operations. For FPGA, the book involved in mathematical operations is a 16-bit integer number. What if there is a decimal number in the mathematical o

A lot of feedback shows that many FPGA beginners are passionate at the beginning, but if they are not getting started for a long time, some people will gradually lose their interest a
This article is originally from V3 College Www.v3edu.org,FPGA training SpecialistIn order to improve the reuse rate of our code, we can write the code of different functions and then connect to the top layer. We give a simple example, the following procedure, we implement the LED water.In the LED module, we first divide the system clock into 1HZ clock, and then use the crossover clock to control the flow of LED lights, but my crossover and led light f
In general, there are two FPGA measurement frequency algorithms: frequency measurement and measurement Week. I used the electronic measurement textbook to find the definition. The frequency measurement is to count the input signal period within a certain period of time, while the measurement week is opposite. It is within the input signal period, count the standard signal period. It can be understood that the frequency measurement uses a slow clock to

Sequence Signal Generator Based on OpenGL
I. Principles
In digital circuits, serial signals are a series of periodic binary signals cyclically generated by synchronous pulses. the logic device that can generate such a signal is called a sequence signal generator. according to the structure, it can be divided into two types: Feedback Shift Type and counting type.A shift-type serial signal generator con
