This application note contains a reference design consisting of HDL IP and Xilinx AdvancedConfiguration Environment (ACE) software utilities that give designers great flexibility increating in-system programming (ISP) solutions. In-system programming support allowsdesigners to revise existing designs, package the new bitstream programming files with theprovided software utilities, and update the remote system through the JTAG interface using theEmbedded JTAG ACE Player.

On the LPC13xx, programming, erasure and re-programming of the on-chip flash can be performed using In-System Programming (ISP) via the UART serial port, and also, can be performed using In-Application Programming (IAP) calls directed by the end-user code. For In-System Programming (ISP) via the UART serial port, the ISP command handler (resides in the bootloader) allows erasure of one or more sector (s) of the on-chip flash memory.

Frequently, voltage reference stability and noise defi nemeasurement limits in instrumentation systems. In particular,reference noise often sets stable resolution limits.Reference voltages have decreased with the continuingdrop in system power supply voltages, making referencenoise increasingly important. The compressed signalprocessing range mandates a commensurate reductionin reference noise to maintain resolution. Noise ultimatelytranslates into quantization uncertainty in A to D converters,introducing jitter in applications such as scales, inertialnavigation systems, infrared thermography, DVMs andmedical imaging apparatus. A new low voltage reference,the LTC6655, has only 0.3ppm (775nV) noise at 2.5VOUT.Figure 1 lists salient specifi cations in tabular form. Accuracyand temperature coeffi cient are characteristic ofhigh grade, low voltage references. 0.1Hz to 10Hz noise,particularly noteworthy, is unequalled by any low voltageelectronic reference.

目前市場(chǎng)上不少的單片機(jī)具有ISP功能。 ATMEL公司最近新推出的AT89SXXXX系列單片機(jī)也提供了一個(gè)SPI串行接口,讓用戶能對(duì)內(nèi)部程序存儲(chǔ)器編程（ISP）。 什么是 ISP ? ISP（In-System Programming）在系統(tǒng)可編程，指電路板上的空白器件可以編程寫入最終用戶代碼， 而不需要從電路板上取下器件， 已經(jīng)編程的器件也可以用ISP方式擦除或再編程。ISP技術(shù)是未來(lái)發(fā)展方向。 應(yīng)一些單片機(jī)愛(ài)好者的需求,現(xiàn)介紹本站開(kāi)發(fā)的利用串口對(duì)89S51及89S52 ISP編程的軟件及最簡(jiǎn)單的硬件連接方法． 下圖是個(gè)簡(jiǎn)化了的硬件連接方法,雖然不能全自動(dòng)的在線編程，但其連接簡(jiǎn)單實(shí)用穩(wěn)定，比較適于初學(xué)的愛(ài)好者DIY

Description: Microsoft?Windows?HTTP Services (WinHTTP) provides developers with a server-supported, high-level interface to the HTTP/1.1 Internet protocol. WinHTTP is designed to be used primarily in server-based scenarios by server applications that communicate with HTTP servers. WinHTTP is also designed for use in system services and HTTP-based client applications. WinHTTP is more secure and robust than WinInet. However, single-user applications that need FTP or gopher functionality, cookie persistence, caching, automatic credential dialog handling, Internet Explorer compatibility, or downlevel platform support should still consider using WinInet.
