Abstract :
The data acquisition system evaluation board is based on embedded Linux. It uses Cypress´s dual port asynchronous static RAM CY7C028V to transmit data between Motorola´s embedded CPU MPC823e and the data acquisition device, and makes Linux 2.4.4 kernel as its micro operation system. This paper firstly introduces how to build dual port asynchronous RAM hardware interface. On the basis of hardware, the design of dual port asynchronous RAM driver program and the test program based on the driver are discussed in detail. The data acquisition system which can perform data acquisition, data transmission and data processing is tested and verified in the end
