FPGA densities have continued to follow Moore's law and can now support a complete multiprocessor system on programmable chip. The benefits of the FPGA include the ability to build a customized MPSoC system consisting of heterogeneous processing resources, interconnects and memory hierarchies that best match the requirements of each application. In this paper we outline a new approach that allows...
Deadlock occurs randomly and is difficult to detect, it always has a negative impact on the effective execution of operating system. This paper uses the principle of adjacency matrix, path matrix and strongly-connected component of simple directed graph in graph theory, gives a model of detecting deadlock by exploring strongly-connected component from resource allocation graph. The experiment shows...
Memory leak has been exposed to be one of the most serious bugs which are hard to locate and fix in computer program. This paper describes three methods of detecting memory leaks in Solaris when programmers do applications. Using dbx can get specific lines of source codes where memory leak occurs and memory leak sizes. MDB and DTrace can inform the users allocation and reclamation of memory blocks,...
