#Today is also a day for salted fish~
When writing UART last time, I felt a problem. Simple Robei EDA simulation actually has no practical application value. At most, it is to familiarize people who have just started EDA with this design and simulation process. When it is used proficiently, the design can actually copy the actual code.
Another headache is that in the actual competition process, it is guaranteed that Robei EDA design simulation-module file generation-import FPGA development environment-realization of functions, such a process is estimated to be impossible, a more realistic process Probably, first write the code and realize the function of the physical work, and then put the software on Robei to hand in the homework. Although this EDA software is easy to use, it is really easy to use, but in terms of ease of use and design habits, it is indeed not acceptable for a while.
So this time I will give up on the update of the EDA module. Let’s talk about a thing that is closely related to the competition but has no major problems with the FPGA-the upper computer (Upper Computer)
Let me talk about the definition of "upper computer". Conceptually, it is the upper computer that sends commands and provides service functions, while the one that receives commands and obeys the control is the lower computer. Here, the concept of the upper computer is very clear, the upper computer is the upper computer that has the control. In most cases, the upper computer is a PC or master. On the interface of the upper computer, a variety of information can be displayed, data information from the lower computer, or control options to the lower computer, and some data processing interface.
With the upper computer, let's talk about the lower computer. The opposite of the upper computer is the lower computer, which receives commands from the upper computer, makes changes to the running state, and then returns the collected data to the upper computer for processing. The lower-level computer here can be a sensor, a hardware microcontroller, or a lower-level computer. The upper computer and the lower computer are only a constraint of the control relationship, not a definite hardware name. A single chip microcomputer
