    Have you ever wanted to copy a file from your Desktop Computer to your handheld Pocket PC? This included any Windows CE version too? Well if so, I will present an easy way to do it here: It s called the Remote Application Programming Interface, or, RAPI in this article. It is touched on in the MSDN but not really explained very well.

  • DVBH發射端信道內碼和調制部分的FPGA設計和實現

    數字電視技術和超大規模深亞微米的系統級芯片設計技術是當前信息產業中最受關注的兩個方向。它們的交叉就是數字電視應用中的一系列系統級芯片和超深亞微米專用集成電路。其中信道處理系統及其相關芯片更是集中了數字信號處理前向糾錯編解碼等數字電視傳輸的核心技術,成為設計和開發整個數字電視系統的關鍵之一。數字高清晰度電視(Digital HDTV)做為第三代電視標準,已成為當今世界高技術競爭的焦點,本文正是從這個交叉點上出發對DVB-H(Digital Video Broadcasting-handheld)標準中所涉及的信道編碼和調制部分進行了研究,重點分析了信道內編碼部分的硬件優化實現。本項目完成了DVB-H傳輸系統信道編碼的FPGA硬件設計和實現,系統所有FPGA硬件電路設計采用了Veillog HDL語言編寫。同時對清華大學數字電視地面傳輸標準DMB-T(Terrestrial Digital Multimedia/TV Broadcasting)中的關鍵技術做了研究,與DVB標準中的相關技術做了對比。 本文首先對DVB.H以及COFDM的相關理論進行介紹和研究。然后針對DVB-H信道編碼調制器中的部分核心算法的FPGA設計和實現進行了詳細的研究工作,包括外編碼、內編碼(卷積刪余)、內交織(包括比特交織和符號交織)、星座映射、幀形成、OFDM調制的部分設計等。相應地對DVB-H信道解碼解調器中的部分算法的FPGA設計的研究工作做了描述,包括符號解交織和比特解交織。同時對清華大學數字電視地面傳輸標準DMB-T外接收機中頻域和時域解交織模塊的FPGA設計實現做了描述。 筆者在項目中完成的主要工作有: (1)與項目組成員合作制定系統框架,劃分模塊。 (2)對所負責的模塊,包括外編碼、內編碼(卷積刪余)、內交織(包括比特交織和符號交織)、星座映射、幀形成、OFDM調制的算法進行研究并加以優化,建立軟件仿真模型,進行FPGA設計,仿真和實現。

  • 手持式高功率電池充電器

      As the performance of many handheld devices approachesthat of laptop computers, design complexity also increases.Chief among them is thermal management—how doyou meet increasing performance demands while keepinga compact and small product cool in the user’s hand?For instance, as battery capacities inevitably increase,charge currents will also increase to maintain or improvetheir charge times. Traditional linear regulator-based batterychargers will not be able to meet the charge currentand effi ciency demands necessary to allow a product torun cool. What is needed is a switching-based chargerthat takes just about the same amount of space as a linearsolution—but without the heat.

  • DN442 I2C可控降壓緊湊型同步DC/DC穩壓器

      The LTC®3562 quad output step-down regulator is designedfor multicore handheld microprocessor applications thatoperate from a single Li-Ion battery. Its four monolithic, higheffi ciency buck regulators support Intel’s mobile CPU P-Stateand C-State energy saving operating modes. The outputvoltages are independently controllable via I2C, and eachoutput can be independently started and shut down. Designerscan choose from power saving pulse-skipping mode orBurst Mode® operation, or select low noise LDO mode. Thespace-saving LTC3562 is available in a 3mm × 3mm QFNpackage and requires few external components.

  • 按鍵開關控制器簡化系統設計

      handheld designers often grapple with ways to de-bounceand control the on/off pushbutton of portable devices.Traditional de-bounce designs use discrete logic, fl ipflops, resistors and capacitors. Other designs includean onboard microprocessor and discrete comparatorswhich continuously consume battery power. For highvoltage multicell battery applications, a high voltageLDO is needed to drive the low voltage devices. All thisextra circuitry not only increases required board spaceand design complexity, but also drains the battery whenthe handheld device is turned off. Linear Technology addressesthis pushbutton interface challenge with a pairof tiny pushbutton controllers.
