Design a circuit of the General register organization in which 16 registers are there from R0 to R15.

(a) Perform the following microoperation and explain the operation in the steps through the diagram properly: - ADD R13, R7, R10.

(b) Explain the control word as per the register configuration given above.

Design the architecture of DMA mode of operation and illustrate how various components

namely, CPU, RAM, DMA Controller and I/O Peripheral interface each other.

Explain addressing modes in detail with example of each.

Explain the modes of transfer on input-output organization.

Enlist major differences that exist between central computer and the peripheral devices.

What role does an interface play in resolving these differences?

Review Conceptual Example 2 before attempting this problem. The moon has a diameter of 3.48 x 106 m and is a distance of 3.85 x 108 m from the earth. The sun has a diameter of 1.39 x 109 m and is 1.50 x 1011 m from the earth. Determine (in radians) the angles subtended by (a) the moon and (b) the sun, as measured by a person standing on the earth. (c) Determine the ratio of the apparent circular area of the moon to the apparent circular area of the sun. These calculations determine whether a total eclipse of the sun is really “total.”
