Based on the high-speed DAS technique with time-interleaved structure, the design and implementation of high-speed DAS for an all-purpose magnetron adaptive test-equipment is proposed in this paper using the method of multi-access time-sharing acquisition control and mapped inner-storage.

Fast processing techniques of large mechanical bitmap based on memory mapping file;

The solving plans of internal memory mapping,OPC and ADO/OLE OB are set forward,and applying occasion of each plan is discussed.

The paper makes an analysis of the memory mapping and address remapping of the S3C2410 processor as well as the process of implementing the vivi Bootloader along with its modification.

Using memory map to speed the rapid of browsing directory

Some key questions of data acquisition and client end connection are solved by means of completely new ideas and ways to optimize the performance of the data server, such as the memory map, network connections based on the TCP/IP protocol and series data transfer mechanism.

Features and memory map of STM32F10x are introduced,and basic principle and the flowchart of IAP driver are analyzed.

The important technologies, bus-sharing technology and memory-mapped files technology, were also adopted in order to acquire, monitor and store data simultaneously at high speed.

Then a careful study was made of the functional design of management agent,of its application of file mapping and synchronism mechanism,and of its alg.
