Abstract	This paper is presented an effective mean to develop driver program under embedded system. The details to driver program under VxWorks embedded system are given and verified by experiments. A reliable, steady and real-time generalized data acquisition and monitoring system with almost one hundred check points on Ion Cyclotron Range of Frequency heating system on the Experiment advanced superconductor tokomak is needed as to details of charging time and system protection. The A/D (analog/digital) data transfer modes of interrupt (INT) and direct memory access (DMA) based on embedded system of PCI data acquisition card are developed with Tornado IDE, as ensures data acquisition with real-time and high rates. Especially using DMA mode improves the performance of data acquisition cards greatly. Multi DAQ cards with PCI(Peripheral Component Interconnect) bus are grouped to plug into host target computer. During the experiments, the data acquisition system based on embedded system runs in good condition. The data acquisition system under DMA mode has gained high speed acquiring sample rate up to limited range. The ICRF data acquisition system not only provides high-speed data acquisition, but also reduces the CPU resource on host target.
