The Boolean function in sum of products form where K-map is given below (figure) is:___________
ABC + B'C' + A'C'
⇒ ABC + B'C' + A'C'
Consider a 3-bit error detection and 1-bit error correction hamming code for 4-bit date. The extra parity bits required would be ________ and the 3-bit error detection is possible because the code has a minimum distance of ________
Fill in the blanks
Many microprocessors have a specified lower limit on clock frequency (apart from the maximum clock frequency limit) because ______
clock frequency can't go below this value.
Many of the advanced microprocessors prefetch instructions and store it in an instruction buffer to speed up processing. This speed up is achieved because _________
prefetching the instructions to be executed can save considerable amount of waiting time.
A simple and reliable data transfer can be accomplished by using the ‘handshake protocol’. It accomplishes reliable data transfer because for every data item sent by the transmitter __________.
in this case receiver has to respond that receiver can be able to receive the data item.
In an 11-bit computer instruction format, the size of address field is 4-bits. The computer uses expanding OP code technique and has 5 two-address instructions and 32 two-address instructions and the number of zero-address instructions it can support is _________
The possibility of no. of encoding taken by two-address instructions = 5×24×24 = 1280
By one-address instructions = 32×24 = 512
So, the possibility of zero-address instructions = 2048 - (1280 + 512) = 256
Macro expansion is done in pass one instead of pass two in a pass macro assembler because _________
all macro definitions are processed during the first pass only due to all macro expansions done during pass 1 only not in pass 2.
The purpose of instruction location counter in an assembler is _______
used to assign storage address to the program's statements.
Complexity of Kruskal’s algorithm for finding the minimum spanning tree of an undirected graph containing n vertices and m edges if the edges are sorted is __________
O(m log n)
Maximum number of edges in a planar graph with n vertices is ________
3n - 6
⇒ (3n - 2) = 3n - 6
The operation which is commutative but not associative is:
