Problems solved by technology

[0003] However, with the advancement of technology, most server applications and even more and more desktop applications require higher and higher throughput and concurrency, and 1GB of storage space obviously cannot meet these high throughput and concurrency requirements , resulting in limited performance and application scenarios of the Java virtual machine, therefore, improving the available storage space of the Java virtual machine has obviously become an urgent problem to be solved

Abstract

Embodiments of the invention provide a method and a device for realizing a 64-bit Java virtual machine. The method for realizing a 64-bit Java virtual machine comprises: receiving Java bytecodes, writing the Java bytecodes in a 64-bit register in a 64-bit format; using a 64-bit assembly instruction set to perform assembly on the Java bytecodes in the 64-bit register in the 64-bit format, to obtain a 64-bit assembly code; and according to the 64-bit format, controlling address jumping of the 64-bit assembly code, and operating the 64-bit assembly code. The method can make the Java virtual machine operate on a MIPS 64-bit platform, and the virtual machine is not subjected to inherent limitation of a MIPS 32-bit system structure and a Linux operation system kernel, so as to improve storage space programs can use.

Description

technical field [0001] The example of the invention relates to a method and device for realizing a 64-bit Java virtual machine. Background technique [0002] At present, the Java virtual machine that can run on the microprocessor (Microprocessor without Interlocked Pipeline Stages, MIPS) platform without internal interlocking pipeline stage only supports the MIPS32-bit version. Due to the inherent limitations of the MIPS 32-bit architecture and the Linus (Linux) operating system kernel, no application can use more than 1GB of memory. [0003] However, with the advancement of technology, most server applications and even more and more desktop applications require higher and higher throughput and concurrency, and 1GB of storage space obviously cannot meet these high throughput and concurrency requirements , resulting in limited performance and application scenarios of the Java virtual machine, therefore, increasing the available storage space of the Java virtual machine has o...
