[Serialization] FPGA OpenGL series instances 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

[Serialization] FPGA OpenGL series instances Conversion of binary and Gray Codes Using Tilde Gray Code features: There is only one difference between two adjacent code groups. Common binary codes and gray codes can be converted to each other. The following is a brief introduction. 8-bit binary code to Gray Code Binary Code Conversion to Gray code: From the rightmost one, one is different from the other on the left, or is used as the value of

1 SRAM Read-Write timing interpretation Memory is overwhelming, and is the size of the computer system (including embedded systems) is not a small part. It is no exaggeration to say that there must be a data transfer process where there is memory, whether it is embedded in the CPU or plug-in, in the code store or program running when it must be necessary. In this section, the experimental object SRAM (Static RAM) is an asynchronous transmission of volatile memory, its read and write transmissio

Any hardware engineer is familiar with FPGA, just like C language is a required course for software engineers. As long as it is an electronic-related student, you must learn the programmable logic course. The full name of FPGA is field programmable gate array, a field programmable gate array, which is a product of further development on the basis of PAL, gal, EPLD and other programmable devices. From the ap

FPGA low temperature cannot start analysisPhenomenon Description: In the medium plate light end machine to do low-temperature test, respectively to the transmission version, the receiving board power-off restart, found that some boards in the -40° can start, and some boards in -20° are not able to start, need to raise the temperature to 0° above to start, The observed phenomenon is that the 4 LED lights that indicate the status are lit, and the

Therefore, the timing constraints of the I/O ports are also import

volumes of digital processing are very large, in order to increase the speed, commands and data spaces are separated to access two spaces using two buses. At the same time, generally, there is high-speed RAM in the DSP. Data and programs must be loaded to the high-speed slice Ram before they can run. To improve the efficiency of digital computing, DSP sacrifices the convenience of memory management and has many poor support for multiple tasks. Therefore, DSP is not suitable for multi-task contr

From: http://tvb2058.spaces.eepw.com.cn/articles/article/item/15358 Although FPGA and CPLD are both programmable ASIC devices with many common features, the differences between CPLD and FPGA have their own characteristics:① CPLD is more suitable for completing various algorithms and logic combinations, while fp ga is more suitable for completing time series logic. In other words,
