As far as integer operations, up to three operations can be issued each cycle. One of the ALUs also handles branch instructions. In the XLP II, there were two simple integer ALUs and a single complex integer ALU unit. Only the complex integer ALU unit was able to perform operations such as multiplication and division. Though unconfirmed, it's suspected that both ALUs can now do complex integer operations as well. |
Vulcan has doubled the number of [[floating point]] units to two and widened them to 128-bit to support [[ARM]]'s {{arm|NEON}} operations (prior design was only 64-bit wide). In theory, Vulcan's peak performance now stands at 8 [[FLOPS]]/cycle or 8 GFLOPS at 1 GHz. | Vulcan has doubled the number of [[floating point]] units to two and widened them to 128-bit to support [[ARM]]'s {{arm|NEON}} operations (prior design was only 64-bit wide).
