Microcontrollers and microprocessor systems which use RISC R

Microcontrollers and microprocessor systems which use RISC (Reduced Instruction Set Computer) systems, have a large quantity of very detailed instructions. TRUE [] FALSE [] An Arithmetic shift right multiplies a signed binary number by 2 TRUE [] FALSE [] In a selective set operation, the bit pattern in B is used to set certain bits in A. If a bit in B is set to 0, that same position in A gets set to 1, otherwise that bit in A keeps its previous value. TRUE [] FALSE [] Overflow occurs on arithmetic shift left when the two most significant bits are the same. TRUE [] FALSE [] When masking a register storing the value 110101 with all zeroes then the result is 000000. TRUE [] FALSE [] Software systems are easier to modify than Hardwired systems TRUE [] FALSE [] A microprocessor has the processor, memory as w ell as input output peripherals on the same chip. TRUE [] FALSE [] In a selective clear operation, the bit pattern in B is used to clear certain bits in A. If a bit in B is set to 1, that same position in A gets set to 0, otherwise it is unchanged TRUE [] FALSE [] A multiplexer with 4 selection lines has 2 inputs and one output. TRUE [] FALSE [] Von Neumann system stores data and program code together in one memory space Disadvantage of only allowing the CPU to access cither data or the program memory at any one time.

Solution

1. False as Reduced instruction set computer(RISC) uses a small, highly optimized set of instructions.

2.False as in arithemetic right shift we Shift right by n bits on a two\'s complement
signed binary number that means dividing it by 2^n

6. True . Software systems are easier to modify than hardwired as software systems can be reprogrammed.

9. False Selection lines=4 so input lines = 2^n=16
