1. What is UART? As one of the three commonly used low-speed buses (UART, SPI, IIC), UART plays an important role in designing various communication interfaces and debugging. UART stands for Universal Asynchronous Receiver/Transmitter, which is mainly used for serial data transmission, and operates in a full-duplex mode. When sending data, it converts parallel data … Read more

When it comes to FPGAs, many people might first think of major FPGA manufacturers like Xilinx and Altera (which has been acquired by Intel). However, there are also other very distinctive FPGA manufacturers, such as Achronix, which specializes in hardware acceleration devices based on FPGAs and high-performance embedded FPGA (eFPGA) semiconductor intellectual property (IP). Thanks … Read more
In a previous article, we mentioned that the semiconductor chips in the industry are typically divided into digital chips and analog chips. Among them, the market size of digital chips accounts for a large proportion, reaching about 70%. Digital chips can be further subdivided into logic chips, memory chips, and microcontrollers (MCUs). We will introduce … Read more
