We propose LightPC, a lightweight persistence-centric platform to make the system robust against power loss. LightPC consists of hardware and software subsystems, each being referred to as open-channel PMEM (OC-PMEM) and persistence-centric OS (PecOS). OC-PMEM removes physical and logical boundaries in drawing a line between volatile and non-volatile data structures by unshackling new memory media from conventional PMEM complex. PecOS provides a single execution persistence cut to quickly convert the execution states to persistent information in cases of a power failure, which can eliminate persistent control overhead. We prototype LightPC's computing complex and OC-PMEM using our custom system board. PecOS is implemented based on Linux 4.19 and Berkeley bootloader on the hardware prototype. Our evaluation results show that OC-PMEM can make user-level performance comparable with a DRAM-only non-persistent system, while consuming 73% lower power and 69% less energy. LightPC also shortens the execution time of diverse HPC, SPEC, and In-memory DB workloads, compared to traditional persistent systems by 4.3x, on average.

In this paper, an English teaching system based on remote network and embedded software is proposed. The purpose is to further improve the intelligence of English electronic education. This paper presents a design method of speech precision automatic comparison system based on multimode control. Firstly, the overall design framework of speech precision automatic comparison system is developed. TMS320VC5509A is chosen as the core control chip. Then the hardware design of the system is developed, including A/D circuit, external storage circuit, power-on loading circuit, system logic decoding control circuit and LCD interface design. Finally, the hardware assembly and software debugging of the system are completed. The experiment proves that this system has good reliability and good correction rate in English distance teaching.
