Electric computer based on storage level structure

Abstract

The computer design based on new storage hierarchical structure comprises: (1) taking adding the nonvolatile semiconductor memory as an independent storage layer into computer system; (2) replacing traditional HD by high-speed nonvolatile semiconductor memory as computer standard large-capacity external storage device; (3) ensuring hardware compatibility with current system; (4) ensuring software compatibility with current system. This invention is elaborate and reliable for bright market future.

Description

technical field [0001] The invention relates to an electronic computer design based on a novel storage hierarchy structure, which belongs to the field of information technology. Background technique [0002] Storage hierarchy is an architecture optimization method widely used in electronic computer structure design. Its basic principle is: inside the electronic computer, a variety of storage devices with different capacities and access speeds are used to form a storage hierarchy, thus forming the entire storage subsystem of the electronic computer. [0003] The storage device at the top of the storage hierarchy will have the highest storage access speed, the smallest capacity, and the highest price per unit storage unit; from the top of the storage hierarchy down, the devices that make up each level of storage are larger in capacity than those above. The first level of storage hierarchy, and the access speed is lower than the upper level. In addition, the devices that make...

Problems solved by technology

This storage hierarchy has basically remained unchanged for more than 20 years since IBM invented the PC. However, with the increasing gap in access speed and capacity between DRAM and hard disks, the traditional storage hierarchy based on this The electronic computer system of the structure faces many serious problems, including performance problems, power consumption problems, data security problems, etc.

[0007] According to the famous Amdahl's law, the overall performance of the system is always limited by the slowest component, and today the overall performance of electronic computer systems is limited by the low-speed magnetic storage devices in the system. With the development of semiconductor technology, although the main memory DRAM The performance of the computer has been greatly improved, but the speed of accessing the hard disk has not been correspondingly greatly improved, so the overall performance of the electronic computer system is bound by the low-speed hard disk device
