  • The low-power design of the digital hearing aid is indispensable to achieve the compact portable device with long battery duration. In this paper, new low-power adaptive filter structure is proposed based on distributed arithmetic(DA). By modifying the DA technique, the proposed decimation filter structure can significantly reduce the power consumption and implementation area. Through Verilog-HDL coding, cell occupation of the proposed structure is reduced to 33.49% in comparison with that of the conventional multiplier structure. Since Verilog-HDL simulation processing time of the two structures are same, it is assumed that the power consumption or implementation area is proportional to the cell occupation in the simulation.

  • We designed a SIMD-DSP/FPU that can efficiently improve multimedia processing performance when integrated into high-performance embedded microprocessors. We proposed partitioned architectures and new schemes for several functional units to reduce chip area. Sharing functional units reduces the area of FPU significantly. The proposed architecture is modeled in HDL and synthesized with a 0.35$\mu\textrm{m}$ standard cell library. The chip area is estimated to be about 100,000 equivalent gates. The designed unit can run at higher than 50MHz clock frequency of CPU core under the worst-case operating conditions.

  • SENT (single edge nibble transmission) is a serial communication protocol between automotive sensors and ECU (electronic control unit). SENT exploits digital waveform, so it has a simple and cheap architecture without transceiver circuits. Usually it is exploited as an embedded communication interface in the sensors. In this paper, a SENT interface was designed in Verilog HDL, fully complying with SAE J2716. It was implemented in FPGA, and verified on a test board. When it was synthesized, the gate count is about 2,500 gates in 0.18um technology.

  • 본 논문에서는 ARM922T Core와 주변장치를 설계할 수 있는 100만 게이트의 FPGA를 내장한 알데라(Altera)사의 엑스칼리버(Excalibur)를 이용하여 DC모터 제어용 SoC를 설계하였다. SoC란 System on Chip의 약자로 하나의 칩 안에 프로세서와 다양한 목적의 주변장치들을 집적하는 것을 말한다. 모터를 구동하기 위한 PWM신호 생성기를 하드웨어 설계언어(Hardware Description Language)로 구현하고 시뮬레이션을 통해 설계모듈을 검증하였다. 이렇게 검증한 PWM 생성기 모듈과 ARM922T Core를 합성하여 SoC를 설계하였다. PWM 생성기 모들을 구성하는 내부의 각 분분을 VerilogHDL로 코딩하여 심볼로 만들어 통합하는 방식으로 설계를 하였으며 실제 모터를 구동하기 위해서 프로세서가 동작할 수 있도록 C언어로 프로그램하여 함께 칩에 다운로드하여 테스트를 하였다. SoC를 기반으로한 시스템 설계의 장점은 시스템이 간단해지고 고속의 동작이 가능하며 회로의 검증 및 다양한 시뮬레이션이 용이하다는데 있다.
