[FPGA] VGA interface to realize AN430 color bar display on LCD screen
1, Introduction to VGA and AN430
1.VGA
VGA(Video Graphics Array) is a video transmission standard launched by IBM with PS/2 machine in 1987. At that time, it had the advantages of high resolution, fast display speed and rich colors, and was widely used in the field of color display. VGA interface is the interface that outputs analog signa ...

RTL concept and common RTL modeling
RTL and integrated concept
RTL (Register Transfer Level) refers to the HDL level of the circuit by describing the logic function from register to register without paying attention to the details of register and combinational logic (such as how many logic gates are used, the connection topology between logic gates, etc.). RTL level is a higher ...

FPGA&ASIC written questions: Fundamentals of digital circuits (13 frequently asked questions)
Topic 1. Differences between bit, byte, word, DWORD and qword
1byte = 8bit
1word = 2byte = 16bit
1dword = 2word = 4byte = 32bit
1qword = 2dword = 4word = 8byte = 64bit
Topic 2. What is the original code, inverse code, complement code, symbol value code. Taking 8bit as an example, the numerical ranges of their respective representati ...
