When executing a Rotate Through Carry Right (RCR) instruction on a 16-bit word operand, how many total bits form the circular shift ring?
Suppose decimal number 35 is shifted 2 bits to the left in binary. What does its new decimal value become?
The bit-shifting operation diagram `| 0 | ---> [ 1 1 0 1 0 0 0 ] ---> [ C ]` (where 0 enters from the left into the MSB and the LSB exits into the Carry Flag) illustrates which instruction?
The bit-shifting operation diagram `[ C ] <--- [ 1 1 0 1 0 0 0 ] <--- | 0 |` (where 0 enters from the right into the LSB and the MSB exits into the Carry Flag) illustrates which instruction?
Numbers of arbitrary bit size (extended precision) can be added using a proper combination of which instructions?
Analogous to addition with carry (ADC), which assembly instruction performs subtraction while factoring in an incoming borrow?
When executing the instruction 'AND AX, BX', how many individual single-bit bitwise AND operations are performed simultaneously across the 16-bit registers?
Which bitwise logical instruction is used with a bitmask to test or check whether specific bits of an operand are set (1) or cleared (0)?
What are the four primary selective bit masking operations performed using bitwise logical instructions?
