1. Balance and exchange between area and speed
The area here refers to the amount of logic resources consumed by a design in the FPGA/CPLD . For FPGA, it can be measured by the consumed FF (flip-flop)...
I have seen some books introducing how to make an op amp into a voltage follower, with the output connected to the inverting phase, while others only briefly mention the same phase. I would like to as...
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]
