Branch instructions in 8085

Branch Instructions in 8085 Microprocessor Video Lecture From Instruction Set and Programming Chapter of Computer Science Instruction set of 8085 microprocessor, Branching group is the fourth group in 8085 for programming,Total 5 groups are there in Get Instruction Set of 8085 Multiple Choice Questions (MCQ Quiz) with answers and detailed solutions. Download these Free Instruction Set Examine these two statements carefully and select the answer using the codes given below: Statement (I): Branch instructions in a microprocessor are Instruction Set • 8085 instruction set consists of the following instructions: • Data moving instructions. • When the EU executes a branch or jump instruction, it transfers control to a location corresponding to another set of sequential instructions. • Architecture & Instruction set of 8085 microprocessor 8085 is pronounced as "eighty-eighty-five" microprocessor. It is an 8-bit microprocessor designed by Intel in 1977 using NMOS technology. It has the following configuration ? ? 8-bit data bus ? 16-bit address bus, which can address upto 64KB ? A There are three groups of instructions in 8085 microprocessor based on the length or size of the instruction. Branch instructions change the sequence of the program execution unconditionally or conditionally. The condition of flags is used to take the decision for conditional branches. 8085 Instruction Set Page 6. BRANCHING INSTRUCTIONS. Opcode Operand Description. Jump unconditionally JMP 16-bit address The program sequence is transferred to However these can be used as software instructions in a program to transfer program execution to one of the eight locations. DATA TRANSFER INSTRUCTIONS Opcode Operand Description 8085 INSTRUCTION SET INSTRUCTION DETAILS Copy from source to destination OV Rd, Rs This instruction copies the contents of the source, Rs register. 3. 8085:branching & logical instruction 3 8085:branching instruction Unconditional Branch Instructions : In Unconditional control transfer instructions, the execution control is transferred to the specified location independent of any status or condition. We have to read the SIM and RIM instructions first to have an idea about the SIM instruction. Let's start! Masking means you manually disable an interrupt, so even if the interrupt occurs, it won't SOD , Serial Out Data. If you remember SOD is the 4th pin in 8085 pin diagram .

The branching instructions alter the normal Unconditional branching insrtructions: Jmp : This instruction is used to jump from one set of programs to another set. e.g: In a 8 bit multiplication Branch Instructions in 8085 Microprocessor Video Lecture From Instruction Set and Programming Chapter of Computer Science In this video, i have covered Branching Instructions in Microprocessor 8085 with following outlines. An Instruction is a command given to the computer to perform a specified operation on given data. The instruction set of a microprocessor is the collection of the Branch Control Group. This group includes the instructions for conditional and unconditional jump, subroutine call and return, and restart. An Instruction is a command given to the computer to perform a specified operation on given data. The instruction set of a microprocessor is the collection of the Branch Control Group. This group includes the instructions for conditional and unconditional jump, subroutine call and return, and restart. 8085 has cheap branching, not like a modern pipelined CPU where branching can be expensive on branch mis-predictions. The mask = n >> 31 or equivalent for branchless abs is useful there and the whole thing is typically only 3 or 4 instructions. (8085 only has shift-by-1 instructions; later ISAs
