- Complex Instruction Set Computer (CISC)
- Minimal instruction set computers (MISC)
- Very long instruction word (VLIW)
- Explicitly parallel instruction computing (EPIC)
- One instruction set computer (OISC)

What are the instructions set of microprocessor?
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 instructions that the microprocessor is designed to execute.
How many groups are there in instruction set of 8085?
Let us take a look at the programming of 8085 Microprocessor. Instruction sets are instruction codes to perform some task. It is classified into five categories.
What are the 5 functional categories of instruction set in 8085 explain each briefly?
These instructions can be classified into the following five functional categories: data transfer (copy) operations, arithmetic operations, logical operations, branching operations, and machine-control operations. An instruction is a binary pattern designed inside a microprocessor to perform a specific function.
What is 8085 instruction set?
Data Transfer Group
| Instruction Set | Explanation | Machine Cycles |
|---|---|---|
| MOV M, r [[H-L]]←[r] | Move the content of register to memory | 2 |
| MVI r, data [r] ←data | Move immediate data to register | 3 |
| LXI rp, data 16 [rp] ←data 16 bits, [rh] ←8 MSBs, [rl] ←8 LSBs of data | Load Register pair immediate | 3 |
| LDA addr [A] ←[addr] | Load Accumulator direct | 4 |
What are the types of instructions set in 8085?
The 8085 instruction set is classified into 3 categories by considering the length of the instructions. In 8085, the length is measured in terms of “byte” rather then “word” because 8085 microprocessor has 8-bit data bus. Three types of instruction are: 1-byte instruction, 2-byte instruction, and 3-byte instruction.
Which among the following is a type of 8085 instructions?
Instruction Set Classification of 8085 Microprocessor
| Description | No. of opcodes | No. of instruction types |
|---|---|---|
| Data transfer Instructions | 83 | 13 |
| Arithmetic Instructions | 62 | 14 |
| Logical Instructions | 43 | 15 |
| Stack Instructions | 15 | 9 |
Which is 3-byte instruction of 8085?
In a 3-byte instruction, the first byte specifies the opcode, and the following two bytes specify the 16-bit address. The 2nd byte holds the low order address. The 3rd-byte holds the high order address. Instructions require three memory locations to store the single byte in the memory.
What are the 3 types of instructions?
A computer must have the following types of instructions:
- Data transfer instructions.
- Data manipulation instructions.
- Program sequencing and control instructions.
- Input and output instructions.
How many bytes of instruction are there in 8085 give one suitable example of each?
In 8085, the length is measured in terms of “byte” rather then “word” because 8085 microprocessor has 8-bit data bus. Three types of instruction are: ◦ 1-byte instruction ◦ 2-byte instruction, and ◦ 3-byte instruction. In 1-byte instruction, the opcode and the operand of an instruction are represented in one byte.
What is the instruction format of 8085?
The 8085 instruction set is classified into the following three groups according to word size: ü One-word or 1-byte instructions ü Two-word or 2-byte instructions ü Three-word or 3-byte instructions
What is the instructionformat in 8085?
The 8085 instruction set is classified into the following three groups according to word size: In the 8085, “byte” and “word” are synonymous because it is an 8-bit microprocessor. However, instructions are commonly referred to in terms of bytes rather than words.
What are the different addressing modes in 8085?
The addressing modes of 8085 microprocessor can be classified into five. They are immediate addressing, register addressing, direct addressing, indirect addressing, and implied addressing. All 8085 addressing modes are described below. Before that what is an addressing mode in a microprocessor.
What is the programming model of 8085?
Programming Model of 8085: The programming model of 8085 consist of an 8-bit accumulator, one flag register, 6 general 8-bit purpose registers , and two 16-bit special purpose registers . These registers are critically required when programming a 8085 processor. The different register in the programming model are explained below:
