The energy consumption optimization of embedded systems can be undertaken in multiple levels of hardware and software. In this paper, based on the energy consumption measurement of embedded software, the generating reasons and influencing factors of embedded software energy consumption on the micro-structure and circuit level of hardware were analyzed firstly. Then, to reduce the energy consumption...
In embedded systems, the frequent execution of software drives the activities of hardware, which causes the energy consumption of systems. In this paper, we first propose an improved C source-level code program energy model by considering the energy consumption of instruction fetching phase, in which a accurate energy algorithm is used. Then, we implement a method to dynamically calculate the run-time...
The RTOS (Real-Time Operating System) is a critical component in the SOPC (System-On-Programmable-Chip), in which the hardware-software unified multi-task management and scheduling of RTOS can significantly improve the performance of SOPC. First, we build a unified scheduling policy based on hardware-software unified multi-task management model. Then, we analyze the shared resources competition problem...
How general the ATS (automatic test system) is influences the application range and the maintenance cost of test systems directly. However, it is the reuse of software that will make the ATS more general. Herein this paper adopts a method of developing software based on software bus; a reconfigurable model of automatic test system is researched and designed. And the interchangeable instrument technology...
