This paper presents the design and implementation of a hardwired OS kernel circuitry inside a Java application processor to provide the system services that are traditionally implemented in software. The hardwired system functions in the proposed SoC include the thread manager, the memory manager, and the I/O subsystem interface. There are many advantages in making the OS kernel a hardware component,...
Publishing scientific results without the detailed execution environments describing how the results were collected makes it difficult or even impossible for the reader to reproduce the work. However, the configurations of the execution environments are too complex to be described easily by authors. To solve this problem, we propose a framework facilitating the conduct of reproducible research by...
In this paper, we advocate the use of code polymorphism as an efficient means to improve security at several levels in electronic devices. We analyse the threats that polymorphism could help thwart, and present the solution that we plan to demonstrate in the scope of a collaborative research project called COGITO. We expect our solution to be effective to improve security, to comply with the computing...
Sparse matrix-vector multiplication (SpMV) is an important computational kernel in many applications. For performance improvement, software libraries designated for SpMV computation have been introduced, e.g., MKL library for CPUs and cuSPARSE library for GPUs. However, the computational throughput of these libraries is far below the peak floating-point performance offered by hardware platforms, because...
