Question
What are wait states in microprocessors, explain.?
Answers
The WAIT state plays a significant role in preventing CPU speed incompatibilities.
Many a times the processor is at a ready state to accept data from a device or location, but there might be no input available. This can lead to wastage of cpu time.
So in such cases when the cpu is ready for an input but there is no such valid data then the system gets into WAIT state. In this scenario the pin 35 ( ready pin )is put into a low state.
As soon as there is some valid data for the 8085 the system comes off the WAIT state and the low state of the READY pin is withdrawn.   Your Comment

  • Q A homeowner is considering placing a 3.5’ deep splash pool on an existing deck. The deck consists of finished 2” X 6” (actual dimensions 1.5” X 5.5”) boards placed on finished 2” X 6” beams. The beams are supported by concrete blocks with centers on a 2’ X 4’ pattern. Therefore, the boards have a span length of 2.0 ft and they support the weight of water contained in a 5.5” X 2’ X 3.5’ rectangular prism. The beams have a span length of 4.0 ft and they support the weight of water and boards in a 2 by 4 ft or 8 ft2 area. The density of water is 62.34 lb/ft3 and the specific gravity of the wood is 0.75. Therefore, the density of the wood is 0.75(62.34) or 46.755 lb/ft3. The modulus of elasticity of the wood is 1.9 E6 lb/in2. Calculate the deflection of both the boards and the beams
