List the unconditional branch instruction in 8086 with examples?
JUMP RET CALL RETI RETN RETF These are unconditional branch instructions By, Satish G.Patil
A Explain the use of Code Segment CS and data segment DS register in 8086 microprocessor?
Code segment (CS) is a 16-bit register containing address of 64 KB segment with processor instructions. The processor uses CS segment for all accesses to instructions referenced by instruction pointer (IP) register. CS register cannot be changed directly. The CS register is automatically updated during far jump, far call and far return instructions. Data segment (DS) is a 16-bit register containing address of 64KB segment with program data. By default, the processor assumes that all data referenced by general registers (AX, BX, CX, DX) and index register (SI, DI) is located in the data segment. DS register can be changed directly using POP and LDS instructions. Code segment (CS) is a 16-bit register containing address of 64 KB segment with processor instructions.

What is the meaning of near and far declaration in microprocessor programming using C?
Programs that are loaded into memory typically have several segments associated with them: the Code Segment (CS), the Stack Segment (SS), the Data Segment (DS), sometimes an Extended Segment (ES), and almost always a Block Started by Symbol (BSS) segment. This question requires that we focus only on the Code Segment (CS). The CS is a segment of memory that contains some of the instructions that are required for the program to execute. If this segment is not large enough to contain the whole program then the program can be loaded into different segments. Such a segment may be 64Kb in size (although the size may differ). Instructions located in these segments are referred to by their offset from the start of the segment, and not by their absolute location in memory. Thus, in order to locate a certain instruction, we need the segment's starting address, and the offset of the instruction in that segment. Whenever a branch (jump, goto) takes place which refers to an instruction that is located in another segment, it is known as a far jump, conversely whenever a jump refers to an instruction that is located in the same segment, it is known as a near jump. The difference referring to the modication of the CS register which contains the address of the current Code Segment for the current running program.
How many bus cycles are required for an unconditional or a conditional jump instruction in 8086 microprocessor to be executed?
when conditional jump instruction is executed it has 10 m/c cycles bt when nt executed it has 7 m/c cycles....while unconditional jump instruction has 10 m/c cycles...
Difference between intersegment and intrasegment jump?
Intrasegment jumps are always between statements in the same code segment. Intersegment jumps can transfer control to a statement in a different code segment. Dr Zeeshan
What happens when branch instruction comes in 8086?
When a branch (or "jump") instruction is executed, the condition codes bits (in the flag register) determine whether or not the Program Counter (PC register) is changed to the Effective Address specified by the instruction; if not, then the PC is unchanged.
Why cant' a segment register be used as a byte register?
There are only a certain (few) number of operations that you can perform on a segment register. Specifically, you can push/pop, and move. That's it. Besides, arbitrarily manipulating segment registers will impact your execution environment - think about what could happen to your program if you changed CS - bad, very bad, unless you also changed IP - and that is called a far jump.

What are advantages of 8086 microprocessor?
The advantages of 8086 microprocessor are:1. It is a 16 bit processor2. it can perform operation of 16 bit data at a time3. It has a pipeline architecture4. It has high sped then 8085 micro processor5. Due to the two different parallel working of processors such as BIU and EU the time is saved
How do you beat Wiggler in Mario and Luigi Bowser's Inside Story?
Attack each red segment so that it turns yellow, then attack the yellow segments to cause lots of damage. Repeat until Wiggler is defeated.
