. 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

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
Note: The writer, Heidiroizen, is a dfjventure partner at Apple, a senior vice president of developer relations and a female entrepreneur.Ms. Roizen proposed eight career principles, including entrepreneurship she said: "Many people with ambition to eliminate the difficulties in the work, the smooth reach of the other side of the dream, it is not right." The reality is that even if you are really easy to succeed, you will be bored. So, find something difficult to do. The beauty of entrepreneursh
The luxurious and brilliant Windows system allows people to throw DOS to a distant memory corner. 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

One or four of the best CS program: Stanford, UC. Berkeley, MIT, CMU

The second type of domestic enterprises in the development stage are generally large in scale, but their business performance has been around for many years. The increment does not increase profits or the increment does not increase profits, the strategy is vague, and the operation efficiency is low, poor execution. In a word, the hollow radish, why does this happen? The entrepreneurial hero began to become the resistan
consumers at the same time. Interactive Advertisements provide more vivid visual and auditory stimulation to consumers than traditional TV advertisements, and combine them with the control and presence of interactive functions, more vivid and interesting interactive ad user experience makes consumers better remember.

It's easy to understand. You don't have to discover this in Harvard University for four years.
However, we know that some merchants will rent expensive places and purchase their goods skillfully. The store is beautifully decorated and a lot of advertising fees are spent, however, they hired some shop assistants who did not know how to listen to others-the shop assistants interrupt the guests, a

from our sight. This will be a huge revolution in the convergence of truth and virtual reality. However, the world we used to change in the past must be completely changed. Perhaps the world of AR still sounds like a picture in a movie, but if we trace its development history, the related research has actually started as early as the 1960 s. The earliest research scholar was Ivan Sutherland, who taught at Harvard University and the University of Utah
Stanley Milgram, a professor of psychology at Harvard University in 1967 also came to this conclusion. The modern version is the same experiment conducted by Columbia University today using e-mail. Some scientists have even demonstrated an evaluable mathematical model from this phenomenon. You may not know Clinton, but with optimization, you only need six people to get to know him.

The ultimate goal of a person is a mixture of a person's potential and deep-rooted values, that is, the final positioning of your life.Second, when formulating the bottom-layer daily goals, we should focus on human nature, operability and controllability, and strive to achieve it easily.Once again,

However, this kind of tracking has little or no obvious value for customers. For example, the convenience of the "pillow" provided by the Ritz hotel for customers may be far less affordable for customers than to spend more than one discount for multiple times., in addition, sometimes this kind of "convenience" seems very mechanical. For example, if a customer asks to create a steak just to taste it, however, in the future, the steak at other chain stores i
