薄膜晶体管液晶显示器(TFT-LCD)具有重量轻、平板化、低功耗、无辐射、显示品质优良等特点,其应用领域正在逐步扩大,已经从音像制品、笔记本电脑等显示器发展到台式计算机、工程工作站(EWS)用监视器。对液晶显示器的要求也正在向高分辨率、高彩色化发展。 由于CRT显示器和液晶屏具有不同的显示特性,两者的显示信号参数也不同,因此在计算机(或MCU)和液晶屏之间设计液晶显示器的驱动电路是必需的,其主要功能是通过调制输出到LCD电极上的电位信号、峰值、频率等参数来建立交流驱动电场。 本文实现了将VGA接口信号转换到模拟液晶屏上显示的驱动电路,采用ADI公司的高性能DSP芯片ADSP-21160来实现驱动电路的主要功能。

This white paper discusses how market trends, the need for increased productivity, and new legislation have accelerated the use of safety systems in industrial machinery. This TÜV-qualified FPGA design methodology is changing the paradigms of safety designs and will greatly reduce development effort, system complexity, and time to market. This allows FPGA users to design their own customized safety controllers and provides a significant competitive advantage over traditional microcontroller or ASIC-based designs. Introduction The basic motivation of deploying functional safety systems is to ensure safe operation as well as safe behavior in cases of failure. Examples of functional safety systems include train brakes, proximity sensors for hazardous areas around machines such as fast-moving robots, and distributed control systems in process automation equipment such as those used in petrochemical plants. The International Electrotechnical Commission’s standard, IEC 61508: “Functional safety of electrical/electronic/programmable electronic safety-related systems,” is understood as the standard for designing safety systems for electrical, electronic, and programmable electronic (E/E/PE) equipment. This standard was developed in the mid-1980s and has been revised several times to cover the technical advances in various industries. In addition, derivative standards have been developed for specific markets and applications that prescribe the particular requirements on functional safety systems in these industry applications. Example applications include process automation (IEC 61511), machine automation (IEC 62061), transportation (railway EN 50128), medical (IEC 62304), automotive (ISO 26262), power generation, distribution, and transportation. 图Figure 1.
