The 8-bit architecture is a microprocessor or computer architecture that has a datapath width or a highest operand width of 8 bits or an octet. These architectures typically have a matching register file with registers width of 8 bits.

[hide]Applications[edit]
As a departure from the older 4-bit microprocessors, 8-bit CPUs found their way to many military applications, scientific instrumentation, complex control and processing systems. 8-bit microcontrollers have been used in just about every electrical consumer product.
8-bit microcontrollers still make up the largest group by revenue - accounting for close to 40% of the microcontroller market total revenue in 2015.
