Recently, a research team hailing from the Institute of Software at the Chinese Academy of Sciences has put forth an innovative ISAX heterogeneous computing system, which is firmly grounded in the RISC-V instruction set. This cutting-edge system makes ingenious use of RISC-V binary rewriting technology. Through this technology, it facilitates the seamless and efficient migration of computing tasks across heterogeneous cores in a transparent manner, all without the need to alter the original source code.

This groundbreaking innovation serves as a potent solution to the performance bottlenecks that have long plagued traditional heterogeneous computing systems. These bottlenecks include issues like hardware resource isolation, where different components struggle to share resources effectively, and excessive runtime overhead, which can slow down the system's overall performance. Moreover, the ISAX system offers vital technical backing to tackle the software and hardware adaptation challenges that arise due to the fragmentation within the RISC-V ecosystem. This fragmentation often leads to compatibility issues and hinders the smooth integration of software and hardware components.
