WebSep 21, 2024 · A CPU, or central processing unit, is the main chip in a computer that carries out commands. It reads and interprets data from memory, performs mathematical and logic operations, and manages input/output devices. The term CPU is often used interchangeably with the microprocessor. The first electronic computers were created in the early 1900s. WebJun 19, 2024 · Clock generators and clock buffers are useful when several frequencies are required and the target ICs are all on the same board or in the same FPGA. In some applications, FPGA/ASICs have multiple time domains for the data path, control plane and memory controller interface, and as a result, require multiple unique reference frequencies.
