Abstract:This paper shows a new design for data acquisition system in automobile engine analysis instrument.Having been compared with some schemes, the system is characteristic of automatism, high-speed, vast-capacity, and real-time. Through adopting ping-pong memory access to DSP and FPGA/CPLD, and setting four modes, the system controls two slices of SRAM to write and read the data converted from A/D alternately. In this way, A/D acquires data uninterruptedly while DSP reads and processes the sample data. Furthermore… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
