The article realization of NAND FLASH control glueless interface circuit based on FPGA,comparing the advantages and disadvantages of the NAND Flash and analysising the function of control interface circuit. The control interface circuit can correct carry out the SRAM timing-input block erase, page reads, page programming, state read instructions into the required operation sequence of NAND Flash, greatly simplifies the NAND FLASH read and write timing control. According to the ECC algorithm,the realization method of ECC check code generation,error search,error correction is described.The function of operate instructions of the NAND Flash control interface circuit designed in this paper is verified on Xillinx Spartan-3 board, and the frequency can reach 100MHz.

The determination of process route is a complex process and one of key techniques of computer-aided process planning. workpiece surfaces are classified. The machining element is determined and ranked according to rules of technological design. Finally, all the machining elements are reorganized and ranked with the comprehensive consideration of freedom constraints of workpiecesand technological equipment. The operation sequence is generated automatically.

Using Data

Abstract This research proposes a framework for automating Maynard Operation Sequence Technique (MOST) studies. This is done by using data available in assembly work instructions, plant layouts and Product Data Management systems. Specifically, an investigation into the information flow requirements for the automated system is performed. One aspect of the information flow is investigated — mapping assembly work instruction to MOST activities and sequence models. A software is developed from the mapping, which acts as a demonstrator to show the usefulness of decision support during MOST analyses. The demonstrated efficacy warrants future efforts towards implementing the remaining facets of the information flow identified.
