There are two problems emerged while multi-core platform become popular in daily life, no matter for high end or low end. The first is how to fully utilize computing resource of these cores without requirement of large modifications of current software design model. The second is about dividing a piece of serial program into parallel program. However, the latter is the responsibility of compiler,...
Chip multiprocessor (CMP) will become more popular in embedded systems. As clock frequency increases, dependency among core blocks rises, which therefore tends to reduce performance of system and be more unstable. Redundancy is a way to improve the dependability of the system. But the traditional methods cannot make full use of the computing capacity of CMP. In this paper, we propose a new redundancy...
This paper proposes a hardware approach to improving information retrieval efficiency on the vector space model. We design a heterogeneous multicore system, within which auxiliary retrieval-oriented intellectual properties (IP) cores perform term counting as basic operations. Moreover, a memory system is also designed to supply data efficiently. Since term counting is a highly frequent operation in...
