A Novel Operating System on Chip With Information Security Support for Embedded System

System-On-Chip (SOC) has provided more powerful functions for embedded systems. ScratchPad Memory (SPM), which is software-controlled on-chip memory, is used in embedded systems to reduce the speed gap between the processors and the memory and the power consumption of memory. ChipOS, a novel operating system on chip with information security support for embedded system, is proposed in this paper. It has a microkernel residing in SPM. This microkernel can execute absolutely. And it can also encapsulate the processor resources and provide virtual resources to General Operating System (GPOS).
