随着当前面向特定领域加速器设计的快速发展,基于加速器的异构系统是计算架构设计发展的新趋势.但复杂的异构系统对编程方式以及处理器和加速器之间的高效交互提出了挑战.如何描述主处理器和加速器的计算任务,降低两者之间的数据传输代价,并让处理器高效地完成对加速器的任务管理调度是保证异构系统性能的关键技术.本文基于一种以数据流为驱动的可重构阵列,基于工作特点,通过对其驱动方式、数据流向、输入输出等进行抽象,提出了一种与主控之间任务管理机制和互连方式,包括硬件的主机接口,软件的任务管理系统等,并基于RISC-V指令集的Rocket Core上实现并验证.
With the rapid development of design for specific fields accelerator
heterogeneous system based on accelerator is a new trend of computing architecture design. However
the complex heterogeneous system challenges the programming mode and the efficient interaction between processor and accelerator. How to describe the computing tasks between the main processor and the accelerator
and how to reduce the cost of data transmission between them
and how to make the processor efficiently complete the task management and scheduling of the accelerator are the key technology to ensure the performance of heterogeneous systems. Based on a reconfigurable array driven by data flow
this paper proposes a task management mechanism and interconnection mode with the master controller by abstracting its driving mode
data flow direction
input and output
including the host interface of hardware
task management system of software
etc.
which is implemented and verified on Rocket Core based on risc-v instruction.
