What are the examples of instruction set?
Examples of instruction set
- ADD – Add two numbers together.
- COMPARE – Compare numbers.
- IN – Input information from a device, e.g., keyboard.
- JUMP – Jump to designated RAM address.
- JUMP IF – Conditional statement that jumps to a designated RAM address.
- LOAD – Load information from RAM to the CPU.
What is Thumb 2 instruction set?
Thumb-2 is an enhancement to the 16-bit Thumb instruction set. It adds 32-bit instructions that can be freely intermixed with 16-bit instructions in a program. The additional 32-bit instructions enable Thumb-2 to cover the functionality of the ARM instruction set.
What is microprocessor instruction set?
Instruction Set of 8085. An instruction is a binary pattern designed inside a microprocessor to perform a specific function. The entire group of instructions that a microprocessor supports is called Instruction Set.
How many types of instruction sets are there in ARM7?
Arm Instruction Set Architecture The Arm architecture supports three instruction sets: A64, A32 and T32.
What is CMP in ARM?
The CMP instruction subtracts the value of Operand2 from the value in Rn . This is the same as a SUBS instruction, except that the result is discarded. The CMN instruction adds the value of Operand2 to the value in Rn . This is the same as an ADDS instruction, except that the result is discarded.
What are the two types of instruction set?
The two main categories of instruction set architectures, CISC (such as Intel’s x86 series) and RISC (such as ARM and MIPS), differ in their instruction complexity and flexibility, but those differences are becoming less defined as technologies are converging.
What is the different between thumb 1 and thumb 2?
Thumb-2 has the performance close to or better than that of the ARM instruction set and has the code density of the original Thumb ISA. In addition to the new 32-bit Thumb instructions, there are several new 16-bit Thumb instructions. Several new 32-bit ARM instructions are introduced at the same time.
What are Thumb instructions?
Thumb instructions are each 16 bits long, and have a corresponding 32-bit ARM instruction that has the same effect on the processor model. Thumb instructions operate with the standard ARM register configuration, allowing excellent interoperability between ARM and Thumb states.
What are the five types of instruction set in 8085 microprocessor?
Instruction Set of Intel 8085 Microprocessor
- Data Transfer Group.
- Arithmetic Group.
- Logical Group.
- Branch Control Group.
- I/O and Machine Control Group.
What is the instruction set of ARM architecture?
Arm Instruction Set Architecture. The Arm architecture supports three instruction sets: A64, A32 and T32. The A64 and A32 instruction sets have fixed instruction lengths of 32-bits. The T32 instruction set was introduced as a supplementary set of 16-bit instructions that supported improved code density for user code.
What is the instruction set of the ARM microcontroller?
Arm Instruction Set Architecture The Arm architecture supports three instruction sets: A64, A32 and T32. The A64 and A32 instruction sets have fixed instruction lengths of 32-bits. The T32 instruction set was introduced as a supplementary set of 16-bit instructions that supported improved code density for user code.
How many instruction sets can an ARM processor support?
Arm architecture can support up to three instruction sets. ARM’s developer website includes documentation, tutorials, support resources and more. Over the next few months we will be adding more developer resources and documentation for all the products and technologies that ARM provides.
What is a move instruction in arm?
12. Move is the simplest ARM instruction. It copies N into a destination register Rd, where N is a register or immediate value. This instruction is useful for setting initial values and transferring data between registers. Syntax: { } {S} Rd, N 12 MOV Instruction 13. This example shows a simple move instruction.
