In computer architecture, 512-bit integers, memory addresses, or other data units are those that are at most 512 bits wide. Also, 512-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size.
There are currently no mainstream general-purpose processors built to operate on 512-bit integers or addresses, though a number of processors do operate on 512-bit data. As of 2013[update], the Intel Xeon Phi has a vector processing unit with 512-bit vector registers, each one holding sixteen 32-bit elements or eight 64-bit elements, and a single instruction can operate on all these values in parallel. However, the Xeon Phi's vector processing unit does not operate on individual numbers that are 512 bits in length.
- Some GPUs such as the Nvidia GTX280, GTX285, Quadro FX 5800 and several Tesla products move data across a 512-bit memory bus.
- Many hash functions, such as SHA-512, have a 512-bit output.
