The memory access limits the performance of stream processors. By exploiting the reuse of data held in the Stream Register File (SRF), an on-chip storage, the number of memory accesses can be reduced. In current stream compilers reuse is only attempted for simple stream references, those whose start and end are known. Compiler analysis from outside of stream processors does not directly enable the...
Dynamic test generation approach is becoming increasingly popular to find security vulnerabilities in software. More and more research institutes and organizations use this approach to find security vulnerabilities in binary code. However, the existing binary level dynamic test generation approaches and tools are not retargetable, and can only find vulnerabilities in binaries for a specific ISA. This...
In this paper, three centralized packet scheduling schemes with fairness-oriented feature are proposed for OFDMA multihop relaying networks, namely Greedy polling with novel starvation restrained (SR-GP), enhanced proportional fairness with SR (SR-EPF) and novel subcarrier pairing with hop balance (HB-SP) scheduling algorithms. SR-GP can bring better fairness than traditional throughput-oriented algorithms...
Stream processors, with the stream programming model, have demonstrated significant performance advantages in the domains signal processing, multimedia and graphics applications. In this paper we examine the applicability of a stream processor to 2-D Jacobi iteration which is widely used to solve partial differential equations, an important class of scientific programs. We first map 2-D Jacobi iteration...
Stream processors, developed for the stream programming model, perform well on media applications. In this paper we examine the applicability of a stream processor to scientific computing applications. Eight scientific applications, each having different performance characteristics, are mapped to a stream processor. Due to the novelty of the stream programming model, we show how to map programs in...
