Attempt ?ve questions. . (5x 10=50)
Show the contents of the registers E, A, Q, SC during the
process of multiplication of two binary numbers
11111(multiplicand) 10101. (multiplier). The signs are
not included.
In an instruction format, there are 16 bits in an instruction
word. Bit O to 11 convey the address of the memory
location for memory related instructions. For non
memory instructions these bits convey various register
or 1/0 operations. Bits 12 to 14 show the various basic
memory Operations such as ADD, AND, LDA etc. Bit 15
Shows if the memory is accessed directly or indirectly.
For such an instruction format draw block diagram of the
control unit of a computer and brie?y explain how an
instruction will be decoded and executed, by thisControl
Unit.
Write an assembly level program for the following
pseudocode.
