Fig. 6.2 shows a block diagram of Internal Architecture of 8086. It is internally divided into two separate functional units. These are theBus Interface Unit (BIU)and theExecution Unit (EU). These two functional units can work simultaneously to increase system speed and hence the throughput. Th...
Timing and Control Unit It controls all the operations of microprocessor and peripheral devices. Depending upon the machine cycles received from Instruction Decoder, it generates 12 control signals: S0 and S1 (Status Signals). ALE (Address Latch Enable).

The internal logic of the 8284A clock generator is depicted in Fig. 5.32. The upper half of the logic diagram represents the clock and reset synchronization section of the 8284A clock generator. It is depicted in Fig. 5.32 that the crystal oscillator has 2 inputs: X1and X2. When a crys...
termed the information sink. The information source can be a computer terminal, a digitizedtransduceroutput, or any other device generating a stream of bits at the rate of one bit every tBseconds.
