> Intel® APX demonstrates the advantage of the variable-length instruction encodings of x86 – new features enhancing the entire instruction set can be defined with only incremental changes to the instruction-decode hardware. This flexibility has allowed Intel® architecture to adapt and flourish over four decades of rapid advances in computing – and it enables the innovations that will keep it thriving into the future.
