Cortex X925’s FPU has six pipes, all of which can handle vector floating point adds, multiplies, and multiply-adds. All six pipes also support vector integer adds and multiplies. Less common instructions like addv are still serviced by four pipes. X925’s FP schedulers are impressively large with approximately 53 entries each. For perspective, each of X925’s three FP schedulers has nearly as much capacity as Bulldozer’s 60 entry unified FP scheduler. Bulldozer used that scheduler to service two threads, while X925 uses its three FP schedulers to service a single thread.
