Q. The difference between a PAL & a PLA is
  • (A) pals and plas are the same thing
  • (B) the pla has a programmable or plane and a programmable and plane, while the pal only has a programmable and plane
  • (C) the pal has a programmable or plane and a programmable and plane, while the pla only has a programmable and plane
  • (D) the pal has more possible product terms than the pla
πŸ’¬ Discuss
βœ… Correct Answer: (B) the pla has a programmable or plane and a programmable and plane, while the pal only has a programmable and plane

Explanation: the main difference between a pal & pla is that pla has a programmable or plane and a programmable and plane, while the pal only has a programmable and plane and a fixed or plane.

Q. If a PAL has been programmed once
  • (A) its logic capacity is lost
  • (B) its outputs are only active high
  • (C) its outputs are only active low
  • (D) it cannot be reprogrammed
πŸ’¬ Discuss
βœ… Correct Answer: (D) it cannot be reprogrammed

Explanation: pal only has a programmable and plane and a fixed or plane. since, pal is dynamic in nature. so, it can’t be reprogrammed.

Q. The FPGA refers to
  • (A) first programmable gate array
  • (B) field programmable gate array
  • (C) first program gate array
  • (D) field program gate array
πŸ’¬ Discuss
βœ… Correct Answer: (B) field programmable gate array

Explanation: the fpga refers to field programmable gate array. field-programmable gate arrays (fpgas) are reprogrammable silicon chips. in contrast to processors that you find in your pc, programming an fpga rewires the chip itself to implement your functionality rather than run a software application.

Q. The full form of VLSI is
  • (A) very long single integration
  • (B) very least scale integration
  • (C) very large scale integration
  • (D) very long scale integration
πŸ’¬ Discuss
βœ… Correct Answer: (C) very large scale integration

Explanation: the full form of vlsi is very large scale integration in which fpga is implemented.

Q. In FPGA, vertical and horizontal directions are separated by
  • (A) a line
  • (B) a channel
  • (C) a strobe
  • (D) a flip-flop
πŸ’¬ Discuss
βœ… Correct Answer: (B) a channel

Explanation: the fpga refers to field programmable gate array. field-programmable gate arrays (fpgas) are reprogrammable silicon chips. vertical and horizontal directions is separated by a channel in an fpga which determines the location of the output.

Q. Applications of PLAs are
  • (A) registered pals
  • (B) configurable pals
  • (C) pal programming
  • (D) all of the mentioned
πŸ’¬ Discuss
βœ… Correct Answer: (D) all of the mentioned

Explanation: applications of plas are as mentioned above and these are performed by using an extra flip- flop with pal.

Q. PAL refers to
  • (A) programmable array loaded
  • (B) programmable logic array
  • (C) programmable array logic
  • (D) programmable and logic
πŸ’¬ Discuss
βœ… Correct Answer: (C) programmable array logic

Explanation: pal refers to programmable array logic consisting of programmable and gates and fixed or gates.

Q. For programmable logic functions, which type of PLD should be used?
  • (A) pla
  • (B) pal
  • (C) cpld
  • (D) sld
πŸ’¬ Discuss
βœ… Correct Answer: (B) pal

Explanation: since pal consists of programmable and gates and fixed or gates and also circuitry working is less.

Q. The flag bits in an ALU is defined as
  • (A) the total number of registers
  • (B) the status bit conditions
  • (C) the total number of control lines
  • (D) all of the mentioned
πŸ’¬ Discuss
βœ… Correct Answer: (B) the status bit conditions
