In this study, the controller using TMS320LF2407 low voltage DSP for motor control is designed and realized. It has 40 MIPS calculating ability and its driving voltage is 3.3 V for low power. The peripheral elements, however usually use 5 V and they need voltage transfer interface. In this study, voltage transformation and reducing noise are studied and space vector PWM is adopted as a motor control scheme. According to these methods, the efforts for software programming and calculation processes are reduced. In addition, the hardware is also simplified by substituting the current control part with software programming. Through this study, the DSP based servo controller increases its ability for high performance multi-function on semiconductor transportation equipments..

The hearing aid chip described in this paper is an analog & digital mixed system. The design focuses on the$\mu$DSP core. This $\mu$DSP core includes internal time delays to two inputs from front and rear microphones. The paper consists of two parts; one is the composure and signal processing algorithm of digital hearing aids and the other is Verilog HDL codes for$\mu$DSP cores. All digital modules in the design were coded and synthesized by Verilog HDL codes which were verified by Mentor Graphics and Synopsis semiconductor chip design tools.

최근의 자동화 추세에 따라 전세계 전력 수요의 50% 이상이 각종 전동기와 관련되어 있다는 추정이 있을 정도로 전동기의 사용은 일반화되어 있다. 특히, 유지 보수 측면에서 경제적인 장점을 지니는 BLDCM, 유도전동기 등의 교류 전동기는 기존에 많이 사용되던 직류전동기를 점차 대치해 가며 그 적용범위를 크게 넓혀가고 있는 상황이다. 광범위하게 이용되는 전동기를 더욱 효율적으로 떠한 더욱 고성능으로 제어하고자 하는 요구도 그 사용의 확대와 더불어 증가되어 최근에는 고성능의 디지털 제어방식을 채용한 드라이버를 이용하여 전동기를 제어하는 것이 일반화되었으며, 특히 1 사이클에 곱셈이 가능하다는 우수한 계산상의 장점을 지닌 DSP를 채용한 전동기 드라이브 시스템은 전에는 구현이 불가능했던 계산량이 많은 고성능의 제어 알고리즘들을 구현 가능하도록 한다는 점에서 큰 관심의 대상이 되고 있다. 이제 전동기 제어 및 드라이브 시스템과 관련된 최근의 주요 이슈들을 알아보고 DSP를 이용한 전동기 드라이브 시스템의 구현 사례, 최근의 전동기 드라이브 시스템용 DSP의 추세 그리고 DSP를 이용한 전동기 드라이브 시스템이 이런 상황에서 어떤 장점을 지닐 수 있는가에 관해 생각해 보고자 한다.

A new 6-axis robot controller with a high-speed 32-bit floating-point DSP TMS32OC30 has been developed in Samsung Electronics. The controller composed of Intel 80386 microprocessor for the main controller, and TKS32OC30 DSP chip for joint position controller. The characteristics of the controller are high sampling rate of 200us and fast reponsibility. The main controller supports MS-DOS, kinematics, trajectory planning, and sensor fusion functions which are vision, PLC, and MAP. The one high speed DSP chip is used for controlling 6 axes of a robot in 200us simultaneously. The control law applied is PID controller including a velocity feedforvard in joint position controller. The performance tests, such as command following, CP, were conducted for the controller integrated with a 6 axes robot developed in Samsung Electronics. The results showed a good performance. This controller can also perform the system control with other controllers, the communication with high priority controllers, and visual information processing.

The performance of a digital baseband signal processing and data transmission rate depends on the modulation technique. In this paper, We implemented DSP communication system for Underwater acoustic communication using by adaptive BPSK modem technique. In order to implement adaptive modem, we suggested SNR detection block. SNR detection block has the reference SNR value that selects between window filter path and matched filter path. In this paper, suggested system is based on software interface and all Hardware(PLL, modem filter, equalizer etc) is implemented by software, exclusive of DSP, A/D, D/A converter, SDRAM and Flash memory.
