When comparing two values via 'CMP DEST, SRC', if the result of the subtraction (DEST - SRC) is zero, the Zero Flag is set (ZF = 1). What does this indicate about the operands?
When subtracting an unsigned source operand from an unsigned destination operand where DEST is smaller than SRC (DEST < SRC), a borrow is generated. Which flag is set?
After subtracting unsigned operands (CMP DEST, SRC), if the resulting flags satisfy 'ZF = 1 OR CF = 1', what relationship holds between DEST and SRC?
After subtracting unsigned operands (CMP DEST, SRC), if the resulting flags satisfy 'ZF = 0 AND CF = 0', what relationship holds between DEST and SRC?
After subtracting unsigned operands (CMP DEST, SRC), if the Carry Flag is cleared (CF = 0), what relationship holds between DEST and SRC?
Which conditional jump instruction is taken if the previous arithmetic/logic operation produced zero, or after a CMP instruction if both operands were equal?
Which conditional jump instruction is taken after a CMP instruction if the unsigned destination operand is below or equal to the unsigned source operand?
Numbers of arbitrary bit-width (e.g., 32-bit or 64-bit) can be added on a 16-bit processor using a proper combination of which instructions?
Analogous to multi-word addition with carry (ADC), which instruction is used to perform multi-word subtraction with borrow?
