APL hardware is hardware that has been designed to natively support APL array operations. This breaks the popular understanding of APL as an interpreted language. Unlike x86, which is targeted to operate on individual scalars one at a time, native APL architectures would be targeted to operate on entire arrays at a time, thereby increasing the speed of APL processing. | |||
