What does the bus do? Plainly, it is used to transfer data between parts of the computer. For example, my main memory stored in the data CPU to use, need a line to pass it, the CPU internal registers between, register and Alu, CU and various parts and so on, and so on many places, in short, the parts need to transfer data The transmitted data is divided into three kinds, corresponding to three kinds of functions of the bus Data bus

to human thinking,So that the computer can have the human logical thinking judgment ability, can think and communicate with human,Abandon the past rely on the code program to run the computer's method, directly to the computer issued instructions.Multimedia technologyThe information processed by traditional computers is mainly characters and numbers. In fact, people are more accustomed to the picture, text, sound, such as many forms of multimedia information.Multimedia technology can set graphi

, contains the arithmetic status of the Alu. As with any other SFR, it can be the operand for any instruction. 8. movlb Move literal to bank select register 9. In addition to the indf operand, each FSR register pair also has four additional indirect operands. like indf, these are "virtual" registers that cannot be indirectly read or written. accessing these registers actually accesses the associated FSR register pair, but also performs a specif

over by the gate, and the take-over is simply to keep it flowing forward.In the same way, we can imagine how the "read" action is achieved? For example, read a byte into a register from a cell in memory. I guess this is the case: The register and memory are connected by 8 lines, through the previous address selector, the memory corresponding unit of the signal has been placed on the connection, and immediately to the register door, but the gate did not open AH. The so-called "read" is simply to

method is called out of the box, the JVM presses a new stack frame into the thread's Java stack, and when the method returns, the stack frame is ejected from the Java stack and discarded.The stack frame consists of three parts: The local variable area, the operand stack, and the frame data area. The local variable area is organized into an array with a single element length of one JVM word (note not a machine word), which is used to hold local variables (locally Variables), including i

As a programmer, always listen to people talking about CPU, memory, main storage, hard disk, motherboard and so on some tall professional terminology, feel oneself weak explode.What is the use of them, now sum it up. Convenient for friends to understand.One.

Summary of the principle of computer composition1. OverviewComputer composition refers to the implementation of the properties embodied in machine architecture, which includes many hardware details that are transparent to the programmer.Including the implementation of instructions, that is, how to take instructions, analysis instructions, take operands, operations, send results and so on.Computers include software systems and hardware systems.Hardware systems include hosts and peripherals.host i

, especially college students, must cultivate their curiosity about life and discover eyes. Only when we "Observe and ponder more, organize and summarize more, think more and share more" can we find some valuable questions around us. Here are some examples.

the operating frequency is the same, the 64-bit CPU processing speed is faster than that of 16-bit and 32-bit. In addition to computing power, compared with 32-bit CPUs, the advantage of 64-bit CPUs is also reflected in the system's memory control. Because the address uses a special integer, a 64-bit cpu alu and a register can process larger integers, that is, a larger address. The traditional 32-bit CPU has a maximum addressing space of 4 GB, which

Currently, most 16-bit single-chip microcomputer is used as the ECU.On the one hand, it collects wheel speed signals into ABSAlgorithm processing: On the other hand, the solenoid valve control command is sent to the implementing agency to handle the pressure-maintaining pressure-decompression of the wheel. At the same time, it also expands the fault detection and solenoid valve monitoring to ensure the ECUNormal operation. Both wheel speed acquisition and algorithm processing and whe
