- Abstract
- In this paper, we present a design on the development of an accelerator device driver for the ultra-high performance processor SoC, which is composed of general-purpose ARM cores and the heterogeneous accelerator, named eXtreme Processing Unit (XPU). We describe our ongoing work on scheduler of accelerator device driver, a software-based OpenCL work group scheduling technique that minimize the scheduling overhead through the concurrent execution of the generation of scheduling metadata and the processing of work group assignment to XPU computing unit and parallel computational task execution in XPU. In addition, we provide a polling-based completion detection mechanism for the OpenCL work group execution, which reduces the scheduling overhead through dynamic update of the polling frequency.
