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...
Home network is becoming an important part of global information infrastructure, where the embedded home gateway is a key information device to implement the interconnection and Internet access between devices in a home. In this paper, a SoC (system-on-a-chip) for embedded home gateway (EHGSoC) is proposed, which provides an integrated processing platform with the support of multiple network protocols,...
In order to realize the test visualization process, we have done research and development on gas turbine engine test visualizations. In this paper, a set of aircraft engine test visible plan is introduced, which has used the object-oriented thought to build basic module, and the three dimensional (3D) module of gas turbine engine and two dimensional (2D) graph of dynamic data tested has been applied...
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...
