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

. The hidapi source also provides a GUI test application which can enumerate and communicate with any HID device attached to the system. The test GUI compiles and runs on all platforms supported by hidapi. What does the API look like? Doxygen HTML documentation can be found here. The API provides an easy method to enumerate hid devices attached to the system, and easy access toFunctionality of the most commonly used hid functions including transfer of input, output, and feature reports.

The smart home gateway and peripheral single-chip microcomputer communication data prepared for the Guangdong Electronic Design Competition need to use TCP/IP communication, so the enc28j60 module is used. In embedded systems, Ethernet controllers are usually one of the hot topics of research. The enc28j60 of microchip has a high application value in embedded systems. The chip integrates Mac controller and PHY and uses the SPI interface, the Ethernet

Developed by filter solutionsnuhertz, nuhertz is an industry leader in filter design software.The trial version is only available for download on the Internet, and the trial period is only 20 days. After the software is used, the software is basically paralyzed. Of course, you can find the serial number if you are careful.The function is very complete. It is worth mentioning that the curve drawn by the filter solutions can be comparable to that drawn by Protel. I basically use the filter wiz pro

MCP2515 IntroductionMCP2515 is an independent can bus communication controller, is the first microchip company independent can solution upgrade device, its transmission capacity is more than microchip company original can controller (MCP2510) twice times, the highest communication rate can reach 1Mbps.

To do an alarm function of East, the request can be remote control to change the content. The watchdog is used because of the high stability requirements of the system.However, the watchdog reset will cause all registers to reset and revert to the default state. Remote control to change the content has also been reset, so only with the use of EEPROM to store alarm signs.I'm using the Mplab X IDE +xc8 compiler, XC8 is a bit different from the PICC in s
