| In terms of software support, although traditional Operating Systems (Windows), programs and games written for the ''x86'' ISA will not run as-is on a ARM device, as both architectures mostly implement the same features (all can do arithmetic/logic operations, memory read/write, even cryptographic and graphic accelerations) and given that modern compilers (//GCC//, //CLang//) have extensive support for almost all of them, an application may be ported to another platform using a simple re-compilation (there are, of course, exceptions in some code bases). | In terms of software support, although traditional Operating Systems (Windows), programs and games written for the ''x86'' ISA will not run as-is on a ARM device, as both architectures mostly implement the same features (all can do arithmetic/logic operations, memory read/write, even cryptographic and graphic accelerations) and given that modern compilers (//GCC//, //CLang//) have extensive support for almost all of them, an application may be ported to another platform using a simple re-compilation (there are, of course, exceptions in some code bases). | ||
