 This trend generally came to an end with the introduction of 32-bit processors, which were a standard in general purpose computing for two decades.64 bit architectures were introduced to the mainstream with the eponymous Nintendo 64 (1996), but beyond this introduction stayed uncommon until the advent of x86-64 architectures around the year 2003, and 2014 for mobile devices with the ARMv8-A instruction set.On 32-bit processors, external data bus width continues to increase.
