一、引言数据从计算机外围设备传输到中央处理单元(CPU)的速率受到一定的限制是今天通用微计算机的缺陷之一。PC8000(NEC,Z80A)也不例处。目前的数据采集系统,是将模-数转换器(ADC)设置于处围设备。在这种情况
I. INTRODUCTION The rate at which data is transferred from a computer peripheral to a central processing unit (CPU) is somewhat limited and is one of the pitfalls of today’s general purpose microcomputers. PC8000 (NEC, Z80A) is no exception. The current data acquisition system, is the analog-digital converter (ADC) set in the peripheral equipment. In this case
