Hello..
Read again, i correct about what about x86 vs ARM processors ?
x86 instruction set is CISC and x86 architecture is RISC(inside)
and ARM instruction set is RISC and ARM architecture is RISC.
The CISC approach attempts to minimize the number of instructions per program, sacrificing the number of cycles per instruction. RISC does the opposite, reducing the cycles per instruction at the cost of the number of instructions per program.
The RISC ISA emphasizes software over hardware. The RISC instruction set requires one to write more efficient software (e.g., compilers or code) with fewer instructions. CISC ISAs use more transistors in the hardware
to implement more instructions and more complex instructions as well.
CISC simplify the software by needing hardware structure to be more complex.
Programming CISC-based computers is easier than in other designs because there is a single instruction for both simple and complex tasks.
Programming in RISC is more difficult and time-consuming than in the other design, because most of the complex instructions are simulated using simple instructions.
So i think that CISC instruction set is less error prone to program than
RISC instruction set, so i think that x86 instruction set is better
for safety.
Thank you,
