1. What is Gray Code
Gray code is a cyclic binary code, or reflex binary code. Gray codes are characterized by a jump in only one data bit when changing from one number to an adjacent number. Because of this feature, metastable states in binary coded count combinational circuits can be avoided. ...

The two-dimensional array in Verilog is very useful. You can use for and generate for together with the two-dimensional array to replace a large number of registers. In fact, a large number of similar registers can be replaced by memory. In Verilog, you can use the two-dimensional array to model the memory.
What resources of FPGA make ...

1. Read operation
SDRAM provides a variety of data reading methods, such as single reading, page burst reading (burst length 1, 2, 4, 8, full page), etc. At present, this paper only explains and simulates the full page burst mode, and provides explanations and simulations of other writing method ...
