Many studies in SoC (System-on-Chip) areas ignore the scheduling of messages exchanged between hardware-software components as a fine level of inter-component communication granularity. Such a message scheduling scheme in hardware-software codesign of SoC systems has received comparatively less attention in the literature despite their importance as an element of a complete partitioning solution....
In this paper, we consider a major problem in the hardware-software codesign of network protocol stacks for real-time embedded systems, which is related to the time-bounded packet delivery channel that guarantees the deadlines of tasks, as well as the timely delivery of packets exchanged between hardware and software tasks. This paper presents a technique to integrate a real-time packet delivery channel...
In this paper, we propose a novel hardware-software codesign technique of network protocol stacks on a SoC (system on chip) platform for providing the QoS (quality of service) functionality. We address that the codesign should guarantee the real-time performance of periodic packets and minimize the average response time of aperiodic packets in order to provide the QoS functionality. We present the...
This paper presents the RCP (reconfigurable hardware-software codesign platform incorporating real-time task management technique) for hardware-software codesign of network protocols in SoC (system-on-chip) based system. In the RCP, we decompose a network protocol suite into real-time application-specific and reconfigurable hardware and software tasks. Such a task decomposition technique can improve...
