CPU is used in the Harvard structure. 2. Harvard StructureThe Harvard structure is a memory structure that separates program instruction storage from data storage, as shown in Figure 1. The CPU first reads the program instruction contents in the program instruction memory, decodes the data address, reads the data in the corresponding data memory, and performs the next operation (usually execution). Program instruction storage and data storage separate, can make instruction and data have differe

content, obtains the data address, reads the data in the corresponding data storage, and performs the next operation (usually execution ). The program instruction storage and data storage are separated, which can make the instruction and data have different data widths. For example, the program instruction of the pic16 chip of microchip is 14-Bit Width, while the data is 8-bit width. Figure 1 Harvard architecture Diagram The Harvard structure micro

This article is about the 1937 timer, just beginning to be crystal oscillator frequency, clock frequency, oscillation period, oscillation frequency, instruction period, instruction frequency and so on the noun around halo. First to solve this problem.Crystal oscillator frequency is the frequency of the oscillator, that is, the frequency of the crystal oscillator, because a single-chip microcomputer has internal external crystal, such as you choose the internal crystal oscillator, then the freque

Recently, I suddenly remembered that I had learned pic, and I had nothing to worry about in the morning. I was planning to review it! Microchip has just released a new mplab x IDE development environment. It is said that it has won any innovation awards, but unfortunately it is praised by hardware engineers for their spam and other words. Try it by yourself. Install and open the interface. After opening it, it will also be dazzling Problems occurred
