摘要

More and more transistors are integrated onto a single chip. Embedded systems have powerful cores compared with traditional ones. On-chip SRAM is also integrated to provide faster memory access, which is controlled by software and called SPM. In this paper, a novel software system on chip is proposed to take use of SPM. This system consists of microkernel, optimized scheduling module, and the support for multi-programs in parallel. Software system on chip resides in SPM, which can avoid many main memory accesses, improve the performance and reduce the power consumption. Experimental results show that the system can achieve the design goal.
