What is jump instruction with example?
The jump instruction transfers the program sequence to the memory address given in the operand based on the specified flag. Jump instructions are of two types: Unconditional Jump Instructions Conditional Jump Instructions. Unconditional Jump Instructions: Transfers the program sequence to the described memory address.What is jump instruction in 8086?
The jump instruction is provided in the 8086 instruction set for implementing control flow operations. In the 8086 architecture, the code segment register and instruction pointer keep track of the next instruction to be fetched for execution.What is jump syntax in assembly?
Jump Instruction
The jump instructions load a new value into the PC register, which stores the value of the instruction being executed. This causes the next instruction read from memory to be retrieved from a new location. The j instruction loads an immediate value into the PC register.
