RISC machines operates on registers to prevent in large amount of interactions with memory

ARM stands for Acorn RISC Machines
RISC
no of registers of each window = l + g + 2c... where l = local register, g = global registers, c = registers which are common no of registers in processor are (l + c)w + g... w = no of registers in windows

RISC architectures generally have fewer instructions that operate directly on memory locations than CISC architectures. So, where a CISC machine will have instructions that operate directly on memory, in RISC this would be implemented as: Load from memory into register, do operation on register, store register back into memory. So a lot of the processing revolves around the Load-Store loop.

The man registers, the computers do the rest.
Registers are memory locations on the microprocessor itself (not in main memory). In RISC architectures generally most operations (add, multiply, etc) must take there input from registers and write their output to a register. Since registers are located directly on the microprocessor, they represent the fastest form of memory in the computer, and also the type of memory available in the least quantity.
When an instruction reaches a microprocessor it arrives at an internal block known as a "microcode sequencer" which is present in CISC architectures. This microcode sequencer then steps through a series of locations in the microcode ROM and issues control signals to the various registers, multiplexers, ALU, etc in the microprocessor. RISC architectures lack this microcode sequencer, but have a similar construct known as a microcode translator or interpreter. Because RISC machines must complete execution in a single clock cycle, there aren't any "steps" to cycle through. Remember that RISC instructions are inherently more simple than CISC instructions.
yes. The ones produced today are fairly basic machines.
