What are special features of ARM architecture?

Memory of ARM processors is tightly coupled. This has very fast response time. It has low latency (quick response) that can also be used in cases of cache memory being unpredictable. ARM processor has management section.

Which feature makes the ARM instruction set differ from RISC set?

ARM differs from RISC-V by including conditional execution, complex indexing modes for accessing memory, its ability to push and pop multiple registers onto/off the stack using a single instruction, optionally shifted source registers, and unconventional immediate encodings.

What are the features of RISC architecture that were used in ARM architecture?

ARM has a number of RISC features, such as a large register set, fixed-length instructions, and a purely load-store architecture. In comparison, 32-bit x86 has six registers that are nominally general-purpose, although a lot of instructions require the use of specific registers.

What are the feature of RISC?

Characteristic of RISC – Simpler instruction, hence simple instruction decoding. Instruction comes undersize of one word. Instruction takes a single clock cycle to get executed. More general-purpose registers.

Which are the different features of ARM instruction set that make it suitable for embedded applications?

There are a number of physical features that have driven the ARM processor design.

• Small to reduce power consumption and extend battery operation.
• High code density.
• Price sensitive and use slow and low-cost memory devices.
• Reduce the area of the die taken up by the embedded processor.
• Hardware debug technology.

What are the features of ARM?

ARM features include:

• Load/store-based architecture.
• Single-cycle instruction execution.
• Consistent 16×32 bit register file.
• Link register.
• Easy decoding and pipelining.
• Power-indexed addressing modes.
• Fixed 32-bit instruction set.

What are the features of RISC architecture?

Is ARM same as RISC?

Two very significant differences between Intel, AMD, ARM, and RISC-V are in the business models and the computing architectures. Intel, AMD, and ARM are based on proprietary IP, and the companies sell and/or license their products. RISC-V is an open specification and platform; it is not an open-source processor.

What is ARM architecture in computer architecture?

ARM architecture. Processors that have a RISC architecture typically require fewer transistors than those with a complex instruction set computing (CISC) architecture (such as the x86 processors found in most personal computers ), which improves cost, power consumption, and heat dissipation.

What is Advanced RISC Machine (ARM)?

Advanced RISC Machine (ARM) Processor is considered to be family of Central Processing Units that is used in music players, smartphones, wearables, tablets and other consumer electronic devices. The architecture of ARM processor is created by Advanced RISC Machines, hence name ARM. This needs very few instruction sets and transistors.

What are the characteristics of RISC architecture?

A typical RISC architecture consists of a large uniform register file, load and store architecture, simple addressing modes and uniform fixed-length instruction fields. Due to this characteristic, we achieve high performance, low code size, low power consumption and low silicon area.

What is the purpose of the ARM architecture Reference Manual?

Since 1995, the ARM Architecture Reference Manual has been the primary source of documentation on the ARM processor architecture and instruction set, distinguishing interfaces that all ARM processors are required to support (such as instruction semantics) from implementation details that may vary.
