• DMA Controller • Latches • Transceivers The basic control bus consists of the signals labeled M/IO (Active Low)‚ RD (Active Low) and WR (Active Low). If the operation to be performed by 8086 is a read (either from a memory location or from a port) the RD (Active Low) goes low and if the operation to be performed by 8086 is a write (either to a memory location or to a port) the WR (Active Low) signal is asserted. If the read or write

The noise produced by the foot-steps of the stranger are collected using the sensor. This sensed signal is then converted into power spectral density and the compared with reference value of our convenience. Accordingly the compared value is processed using a microprocessor‚ which sends appropriate signals to the main node. Thus the stranger is identified at the main node. A series of interface‚ signal processing‚ and communication systems have been implemented in micro power CMOS circuits. A micro

and digital signals are mathematical representations of reality and is useful when we want to process information. We can recognize whether or not something is analog or digital by wave forms. Digital signals often show square shapes and analog shows no obvious pattern but sometimes shows a recognizable shape like a sine wave. Because of this‚ we can sometimes form an opinion about the type of signal by recognizing wave forms. There is no absolute certainty‚ by just examining a real signal pattern and

Synchronous Vs Asynchronous Design Much of today’s logic design is based on two major assumptions: all signals are binary‚ and time is discrete. Both of these assumptions are made in order to simplify logic design. By assuming binary values on signals‚ simple Boolean logic can be used to describe and manipulate logic constructs. By assuming time is discrete‚ hazards and feedback can largely be ignored. However‚ as with many simplifying assumptions‚ a system that can operate without these assumptions
