main memory, two registers Mar and Mdr,mar are used to store the address of the storage unit to be accessed, and the MDR is a memory data register, which is used to store the data taken from a memory unit and the data to be written to a memory unit, and the CPU is added to the control signal for the specific fetch and write action. The operator consists of at least 3 registers and an arithmetic logic unit

present in the MDR:Mdr:memory data Register to hold the CPU reading or writing to the storage unit (data is stored)7. Finally, the control bus is connected to the control logic in the memory to receive read-write signals from the CPU or transmit the completed signals to the CPU feedback.8. Baidu: The main memory data register (MDR) in the computer and the memory address register (MAR) Help to complete the communication between the CPU and the primary

OverviewWhen accessing a storage unit according to the address in Mar, address decoding, driving, etc. are required to find the unit to be accessed. The readout also passes through the readout amplifier to send the stored word of the selected unit to the MDR. When writing, the data in the MDR must also be written to the circuit in order to actually write to the selected unit.Main memory structureThe main me

memory that exists between main memory and CPU, consisting of a static memory chip (SRAM), a smaller capacity but much higher than main memory, close to the CPU speed, because I/O device to main memory request level is higher than the CPU, so the CPU waits for I/O device to visit the phenomenon , in order to avoid the CPU and I/O device scrambling for the visit, main memory to the CPU to take the information forward to the cache, once the host and I/O device Exchange, the CPU can directly from

of TB patients in China is about 1.3 million, and the number of TB deaths is 130,000 per year, surpassing the combined death toll of other infectious diseases. At the same time, China is one of 22 countries with severe TB prevalence and one of the 27 countries with severe MDR-TB prevalence worldwide.The study found that Mycobacterium tuberculosis can survive 6-8 months in dry sputum. It is deduced that the sputum and saliva of people infected with TB

Machine Word Length: The number of bits that the CPU can process data at a time, usually related to the number of registers of the CPU.Storage Word Length: The number of bits of binary code stored by a storage unit (storage address) in memory, that is, the number of MDR in memory.Instruction word Length: The number of bits of the computer instruction character.Data word Length: The number of bits occupied by the computer data store.Note: von Neumann m

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

. If there is an operating system with its own drive, the first use, still can not be normal or can not meet the application needs, the use of equipment with the drive; C. Replace the equipment, you should first uninstall the drive and then replace. Uninstall the drive, uninstall from Device Manager, uninstall from Safe mode, and delete in the INF directory, and finally uninstall through the registry; D. When updating drivers, if there is a problem with the direct upgrade, you must uninstall and

Computer disk to install a variety of installation software files, if there is a problem with disk file access, it is necessary to consider whether the disk media is damaged, the file saved on it is complete and so on. As an internet café, this is the basic work of checking disk partition access, making the following recommendations for checking partitions on a disk. 1. When the hard disk capacity is greater than 64GB, if you want to repartition or view the partition, you will need to use the F
