Why do we need different processor architectures?
Workstation/Server CPU architectures It is dedicated to run a specific software (server software like httpd, mysql etc.). Even if other processes run we need to give server process priority therefore there is a need for new scheduling scheme and thus we need operating system different than general purpose one.

Is ARM similar to MIPS?
MIPS and ARM are two different instruction set architectures in the family of RISC instruction set. Although both the instruction sets have a fixed and same instruction size, ARM has only 16 registers while MIPS has 32 registers. MIPS has no equivalent instruction to the ARM MOV instruction.
Is ARM a computer architecture?
The Arm architecture is a family of reduced instruction set computing (RISC) architectures for computer processors. It is the most pervasive processor architecture in the world, with billions of Arm-based devices shipped every year, from sensors, wearables and smartphones to supercomputers.
Which features does ARM have in common with many other RISC architectures?
ARM has a number of RISC features, such as a large register set, fixed-length instructions, and a purely load-store architecture.
What is a microarchitecture in computer architecture?
It is the combined implementation of registers, memory, arithmetic logic units, multiplexers, and any other digital logic blocks. All of this, together, forms the processor. A microarchitecture combined with an instruction set architecture (ISA) makes up the system’s computer architecture as a whole.
Do all microarchitectures have the same ISA?
Different microarchitectures can implement the same ISA, but with trade-offs in things like power efficiency or execution speed. The most basic processor will include a register file, an ALU, system memory, and a control unit that allows the processor to make decisions based on the instruction it’s executing.
What are the advantages of 32 bit x86 processors?
Many additional powerful and valuable new instructions. Intel’s second generation of 32-bit x86 processors, introduced built-in floating point unit (FPU), 8 KB on-chip L1 cache, and pipelining. Faster per MHz than the 386. Small number of new instructions.
What are the key features of Intel Core i5 processor?
Multithreading, multi-core, 8 fine-grained threads per core of which 2 can be executed simultaneously, 2-way simultaneous multithreading, SMP, 8 cores per chip, out-of-order, 4 MB L3 cache, out-of order, Hardware random number generator
