The invention focuses on componentization embedded software and provides the componentization embedded software energy consumption estimation model based on a Markov chain by regarding the running process of an embedded software system as a set of states from the angle based on states. The componentization embedded software energy consumption estimation model is characterized by firstly aiming atovercoming defects of low accuracy of software state transition probability caused by subjective judgment, classifying common software architecture styles, determining the state transition probability of the software in different styles, generating a software state transition probability matrix, adjusting a non-formal probability matrix to a formal probability matrix when the software state transition probability matrix is the non-formal probability matrix, estimating the average energy consumption of the embedded software according to the measured average component energy consumption value, and ...

The invention discloses an energy consumption related software/hardware partition-oriented hierarchical control and data flow graph modeling method based on the research on conventional control and data flow graphs, and aims to provide support for the energy consumption optimization research and development of embedded software. For a C programming language, energy consumption related software/hardware partition modeling is performed by adopting a software/hardware partition-oriented hierarchical control and data flow graph method; and experimental results show that: compared with normal task graphs, a directed acyclic graph established through the energy consumption related software/hardware partition-oriented hierarchical control and data flow graph can perform certain granularity transformation as required and reasonably process a cycle structure for the C programming language, so the directed acyclic graph is favorable for obtaining an optimal partitioning result by a partitioning algorithm ...

Unified dispatching algorithm of reconfigurable system software/ hardware task based on placement cost

Номер: CN0101944049A

The invention discloses a unified dispatching method of a reconfigurable system software/ hardware task based on placement cost. Aiming at the deficiency of the on-line dispatching method of the current reconfigurable task system, the invention considers three costs, i.e. performing time on an FPGA by the hardware task, occupied FPGA area and the fragment situation of the FPGA; and in addition, the invention also considers the unified dispatching method of the software/ hardware tasks. In the dispatching process, when the cost of the hardware task exceeds the preset threshold, the hardware task is refused to operate on the FPGA, which is realized by utilizing a CPU to perform the corresponding software task. By reasonably refusing certain tasks with larger cost, the invention can improve the task dispatching success rate on a whole. Experiments show that the method can obtain higher task deadline reliability compared with the existing method.

The invention provides a position probability distribution-based energy consumption model of a network-on-chip (NoC) directory protocol by performing deep analysis on a Cache coherence common directory protocol on the basis of study on the energy consumption model of a NoC directory energy consumption model in multi-processor system-on-chip (MPSoC). In consideration of the independence of directory information from data block node position distribution, the node position in NoC of a data block is fixed, a data transmission probability matrix of data transmission between any nodes is calculated, and the energy consumption at one time of data block transmission in the directory protocol can be obtained accurately by combining energy consumption of a routing unit, connection energy consumption and a network topological structure. Experiments show that the model provided by the invention can effectively calculates the energy consumption of different directory protocols in a Mesh network with ...
