High-performance microprocessor register and elastic memory address protective method thereof

Abstract

The invention discloses a high-performance microprocessor register and an elastic memory address protective method thereof. The method comprises the following steps: assigning registers No.37, No.38 and No.39 and allocating memory intervals; checking whether the content of the register No.14 is less than the intermediate page value of the register No.39; checking whether the page number of the register No.16 is within the page number range of the registers No.0 to No.37; checking whether the page number of the register No.18 is within the page number range of the registers No.37 and No.38; checking whether the content of the register No.20 is within the intermediate page values of the registers No.38 and No.39; a processor sends the abnormal registers to an abnormal interrupted register, the command page of the present processor is No.18, and the instruction pointer is No.17, and the processor interrupts handling routine through performing abnormality of an operating system. On the premise that the instruction set is not changed, the high-performance microprocessor register can be upgraded easily; a simple assembly line design and a compact assembly line architecture are adopted, so that the time of each command can be reduced in a better manner; and at the same time, multi- sending is supported, so that the operating rate of the processor is improved, the memory space is effectively allocated, and illegal access of an application program is effectively prevented.

Description

technical field [0001] The invention relates to a high-performance microprocessor register and a memory address elastic protection method thereof. Background technique [0002] Processors are at the heart of the contemporary computer industry. Processors are broadly divided into two categories: RISC processors and ICS processors. In high-performance processing platforms, RISC processors are widely used, such as: PAD, high-performance servers, desktop platforms, embedded platforms, etc.; however, the use of complex instruction set processors is relatively small, generally only used for Low-performance servers and desktop platforms, etc. The main reason is that the instruction length of the reduced instruction set processor is unchanged, the instruction format is small, the number of registers is large, and the number of instructions is small, which can make the processor process more streamlined. It has the characteristics of simple design, high efficiency, easy testing, a...

Problems solved by technology

[0008] 1) When the memory of the computer is small (such as PDD, embedded platform), if the fixed-length memory is large, the memory used by the application program will be very small, which will cause a waste of valuable memory resources and cause the memory not to be used. fair use;

[0009] 2) When the memory of the computer is large (such as in high-performance servers and large-scale computers), and its operating system kernel is also large, it will cause the situation that the operating system kernel cannot be completely protected by the processor kernel;
