| Abstract(in English) | Heterogeneous multi-core architecture that consists of processors, memory modules, and I/O devices with various sizes, functions, and speeds is one of attractive solutions for embedded systems. In particular, a control mechanism that supports low-latency and high-throughput I/O processing is required for various I/O devices on the heterogeneous multi-core processors. In this paper, we design and implement a dedicated I/O processor for heterogeneous multi-core architecture with various I/O devices. The dedicated I/O core has a hardware mechanism which is in charge of efficient I/O request management and communication with I/O devices. Evaluation results show that the dedicated I/O core improves the I/O access latency and throughput compared with software-based I/O processing. |
