A programmable digital signal processor (PDSP) is a SPECIAL-purpose microprocessor with specialized architecture and instruction set for implementing DSP algorithms. Typical architectural features include multiple memory partitions (onchip, off-chip, data memory, program memory, etc.), multiple (generally pipelined) arithmetic and logic units (ALUs), nonuniform register sets, and extensive hardware numeric support [1,2]. Single-chip PDSPs have become increasingly popular for real-time DSP applications [3,4].

提出一种基于凌阳单片机的步进电机加减速的控制方法。采用凌阳科技推出的16位结构工控单片机SPMC75F2413A为控制器，由Allegro公司生产的两相步进电机专用驱动器件SLA7042M构成步进电机的驱动电路，在传统的3段直线加减速控制算法基础上增加至7段S形曲线加减速过程，控制步进电机的启动和停止。实验结果表明，该控制方法克服了直线加减速中不连续、易造成系统冲击的问题，整个系统实现柔性控制，电机启动、停止连续性能提高30%。 Abstract: The method of controlled stepping motor is referred based on SPMC75F2413A MCU， which adopts the 16 knots SPMC75F2413A MCU as the controller. The SPECIAL-purpose actuation chip SLA7042M of two stepping motor produced by Allegro Corporation constituted to actuation electric circuit. The purpose of increasing to seven section of S shape curve based on the traditional three sections of straight line is to control the start and stop process of stepping motor. The experimental results show that the control method solves easy to pull-out and overshot problems. The overall system realizes flexible control， and the performance of motor start or stop continuity is increased 30%

ABAQUS is a general purpose finite element analysis program which is widely used to analyses mechanical, structure and civil engineering problems. Abaqus has some special feature for analysing fracture mechanics problems, and therefore it is a main tools for the FE-analysis in the Fracture Group at the Mechanical Engineering at Glasgow Universtity. The software which can transfer data from Abaqus into a Matlab readable environment has been developed as a part of a research program in Constraint Estimation in Fracture Mechanics. This research program was funded by a grant from the Defence Research Agency through Prof. J. Sumpter.

WHAT MIME64 IS: MIME64 is an encoding described in RFC1341 as MIME base64.Its purpose is to encode binary files into ASCII so that they may be passedthrough e-mail gates. In this regard, MIME64 is similar to UUENCODE.Although most binaries these days are transmitted using UUENCODE, Ihave seen a few using MIME64, and I have had requests from friends thatI decode MIME64 files that have fallen into their hands. As long assome MIME64 continues to exist, a package such as this one is usefulto have.
