The GL823K integrates a high speed 8051 microprocessor and a high efficiency hardware engine for the best data transfer performance between USB and flash card interfaces. Its pin assignment design fits to card sockets to provide easier PCB layout. Inside the chip, it integrates 5V to 3.3V regulator, 3.3V to 1.8V regulator and power MOSFETs and it enables the function of on-chip clock source (OCCS) which means no external 12MHz XTAL is needed and that effectively reduces the total BOM cost.

基于DSP28035的高速永磁无刷直流电机驱动系统，包括论文和软硬设计资料。摘要参赛作品为基于DSP28035的高速永磁无刷直流电机驱动系统。该系统以一台额定转速60 krpm的高速永磁无刷直流电机、交错并联的Buck电路以及全桥电路为硬件平台，以DSP28035为控制核心，实现了调压调速功能和基于坐标变换的无位置传感器新技术。为实现该系统要求，本作品充分利用了DSP28035的资源例如：CLA模块，模拟比较器、HPWM模块以及AD转换模块等。AbstractThis work is the drive system for a high speed permanent magnet burshless dc motor based on DSP28035. The hardware platform consists of a BLDC motor(rated speed is 60000rpm), a Buck circuit and an inverter. Under the control of DSP28035, this system can achieve the goal of adjusting the motor’s speed with voltage and the function of sensorless control based on the coordinate transformation. By making full use of resources of the core, such as CLA, analog comparator, HPWM and AD converters, the whole system can meet the requirements.1 引言高速永磁无刷直流电机驱动系统由于基波频率较高（一般在1kHZ以上），利用逆变桥斩波进行调速的控制方式通常会受到开关管开关频率的限制，因此该系统多采用三相全桥前级加Buck电路进承担调压调速的功能，而三相全桥主要承担逻辑换相的功能。然而，传统Buck电路所需电感的体积较大，增加了系统的体积，降低了系统的功率密度。

VME has been the de-facto bus standard for Commercial off the Shelf(COTS ) Circuit Card Assemblies since the 1980's. VME boards have proven to be remarkably capable of evolving to support newer technologies with innovations such as VME Subsystem Bus, PCI Mezzanine Cards(PMC's) and VME320.However, advances in technologies, appearing particularly in interconnects, have demonstratedthe need for an advance in system development. This advance needs to accommodate high speed interconnect, particularly serial interconnects, and higher power delivery in concert with better heat removal.
