What is 8085 microprocessor instruction set?
Intel 8085 Instructions An instruction of a computer is a command given to the computer to perform a specified operation on given data. In microprocessor, the instruction set is the collection of the instructions that the microprocessor is designed to execute.
What is 8051 assembly language?
Assembly Language is a pseudo-English representation of the Machine Language. The 8051 Microcontroller Assembly Language is a combination of English like words called Mnemonics and Hexadecimal codes. It is also a low level language and requires extensive understanding of the architecture of the Microcontroller.
What is the architecture of 8051 instruction set?
An 8051 Instruction consists of an Opcode (short of Operation – Code) followed by Operand(s) of size Zero Byte, One Byte or Two Bytes. The Op-Code part of the instruction contains the Mnemonic, which specifies the type of operation to be performed.
How many instructions are there in 8085 instruction set?
– The 8085 uses a total of 246 bit patterns to form its instruction set. – These 246 patterns represent only 74 instructions.
What is the function of Dad instruction in 8085 microprocessors?
In 8085 Instruction set, DAD SP instruction is a special case of DAD rp instruction. In this instruction contents of HL and SP will get added and sum thus produced will get stored onto HL register pair. It occupies only 1-Byte in memory.
Which are the data transfer instructions of 8051?
The 8051 microcontroller has an 8-bit opcode which gives it the ability to handle 2^8(255) instructions….List of data transfer instructions.
| Operation | Mnemonics | Description |
|---|---|---|

What is Intel 8085 instruction set?
Intel 8085 Instructions. An instruction of a computer is a command given to the computer to perform a specified operation on given data. In microprocessor, the instruction set is the collection of the instructions that the microprocessor is designed to execute. The programmer writes a program in assembly language using these instructions.
What is the 8051 instruction set manual?
The 8051 Instruction Set Manual explains the standard 8051 instructions. The 8051 Instruction Set is supported by the Keil Ax51 Macro Assembler and the in-line Assembler of the Keil Cx51 Compiler. This manual contains the following chapters: Architecture Overview describes the memory layout and CPU registers of several 8051 variants.
How to perform multiplication in 8051?
Solution: Multiplication can be performed by adding the multiplicand repeatedly, as many times as that of multiplier. Consider the below table lists the conditional jumps instruction used in 8051
How many flip-flops are there in an 8085 microprocessor?
There is a set of five flip-flops which indicate status (condition) arising after the execution of arithmetic and logic instructions. These are: The symbol and abbreviations which have been used while explaining Intel 8085 instructions are as follows: 16-bit address of the memory location. One of the register pairs.
