A complete design for a data acquisition card for the IBM PC is detailed in this application note. Additionally, C language code is provided to allow sampling of data at speed of more than 20kHz. The speed limitation is strictly based on the execution speed of the "C" data acquisition loop. A "Turbo" XT can acquire data at speeds greater than 20kHz. Machines with 80286 and 80386 processors can go faster than 20kHz. The computer that was used as a test bed in this application was an XT running at 4.77MHz and therefore all system timing and acquisition time measurements are based on a 4.77MHz clock speed.

80386处理器是Intel公司80x86发展史上的里程碑,它不但兼容先前的8086/8088,80186,80286处理器,而且也为后来的486,Pentium(586),Pentium Pro(686)的发展打下了坚实的基础,对于我们程序员来讲更重要的是:我们关心80386在指令上到底有哪些扩展呢?80386有哪些寻址方式呢?毫无疑问,它不但兼容了8086的所有指令,而且还对它们进行增强.
