. The purpose of cache is to speed up and cache commands, so you do not need to fetch them in low-speed memory. X86 cache is continuous, but ARM divides L1 cache into two parallel segments, I-Cache and D-Cache. This memory structure separates program instruction storage from data storage is called the Harvard architecture ), the von noriman architecture, which combines the program instruction memory and data memory, is called the von norann architectu

to be put on the agenda, learning to enrich your mind with new knowledge. The second aspect is to establish your own influence in the industry. Excellent Talents in every industry have their own circles. For example, Harvard Business Review Network, professional manager network, and business personnel network are all places where relevant talents gather. Why does it take tens of thousands of people to attend a class? Why can some people use their own

However, the real valuable things won't easily exit the stage of history. debug is one of these classic works. From the old DOS to today's Windows XP, debug has been closely following Microsoft's operating system, quietly lying in the system folder. Maybe you don't care about it at ordinary times, but if you want to become a system master that everyone envy, we have to wake up this long-sleeping com

operation is much more troublesome than EEPROM, so the more user-friendly MCU design will integrate flash and EEPROM two non-volatile memory, the low-cost design often only involves flash, while the early electroerasable mcu was in the eeprm structure, which has basically been discontinued. In the internal circuit of the chip, flash and EEPROM have different circuits and address spaces, and their operation methods and commands are naturally different, regardless of the Von noiman structure or

Convention: cs = computer science (department ). In general, the first 20 cs can be divided into three waves: One or four of the best CS program: Stanford, UC. Berkeley, MIT, CMU 2. The first 10 of the six others: uiuc, Cornell, U. of Washington, Princeton, U.Texas-Austin and U. of Wisconsin-Madison, among which uiuc, Cornell, U.Washington and UW-Madison almost never made the top 10. 3. Other excellent Cs: Caltech, U. of Maryland at CP, ulinoleic, brown, Har
