Overview
The 750 is targeted for high performance, low power systems and supports the following power management
features: doze, nap, sleep, and dynamic power management. The 750 consists of a processor core and an
internal L2 Tag combined with a dedicated L2 cache interface and a 60x bus. The L2 cache is not available
with the 740.
