EV-DO

EVDO(EV-DO)實際上是三個單詞的縮寫:Evolution(演進)、DataOnly。其全稱為:CDMA20001xEV-DO,是CDMA20001x演進(3G)的一條路徑的一個階段。這一路徑有兩個發展階段,第一階段叫1xEV-DO,即“DataOnly”,它可以使運營商利用一個與IS-95或CDMA2000相同頻寬的CDMA載頻就可實現高達2.4Mbps的前向數據傳輸速率,已被國際電聯ITU接納為國際3G標準,并已具備商用化條件。第二階段叫1xEV-DV。1xEV-DV意為“DataandVoice”,它可以在一個CDMA載頻上同時支持話音和數據。

    Writing Your First ASP Application ( Quick Start ) (Page 1 of 8 ) There are many tutorials out there that show you how to program in ASP. Some of them are good, and some are bad. Some of them are downright terrible. In any case, you ve read a bit about ASP and now you are ready to build your first application. But where do you start? In my own experience, I have found that I find it easier to learn something if I actually work with it hands-on. Just reading a book or documentation doesn’t give you the practical knowledge you need to be able to rush off and start creating applications. In this article, I will discuss the creation of a very simple application. I will cover what the application will do, how we will approach writing it, demonstrate in code how we will do it, and discuss additional features that could be added to it.

  • The ability to write efficient, high-speed arithmetic routines ultimately depends upon your knowled

    The ability to write efficient, high-speed arithmetic routines ultimately depends upon your knowledge of the elements of arithmetic as they exist on a computer. That conclusion and this book are the result of a long and frustrating search for information on writing arithmetic routines for real-time embedded systems. With instruction cycle times coming down and clock rates going up, it would seem that speed is not a problem in writing fast routines. In addition, math coprocessors are becoming more popular and less expensive than ever before and are readily available. These factors make arithmetic easier and faster to use and implement. However, for many of you the systems that you are working on do not include the latest chips or the faster processors. Some of the most widely used microcontrollers used today are not Digital Signal Processors (DSP), but simple eight-bit controllers such as the Intel 8051 or 8048 microprocessors.

  • This leon3 design is tailored to the Altera NiosII Startix2 Development board, with 16-bit DDR SDR

    This leon3 design is tailored to the Altera NiosII Startix2 Development board, with 16-bit DDR SDRAM and 2 Mbyte of SSRAM. As of this time, the DDR interface only works up to 120 MHz. At 130, DDR data can be read but not written. NOTE: the test bench cannot be simulated with DDR enabled because the Altera pads do not have the correct delay models. * How to program the flash prom with a FPGA programming file 1. Create a hex file of the programming file with Quartus. 2. Convert it to srecord and adjust the load address: objcopy --adjust-vma=0x800000 output_file.hexout -O srec fpga.srec 3. Program the flash memory using grmon: flash erase 0x800000 0xb00000 flash load fpga.srec
