4.4.4 BP135_AXI2APB component
This section describes the BP135_AXI2APB component.
BP135_AXI2APB - about
This LISA+ component is a model of r0p0 of the PrimeCell Infrastructure AMBA 3 AXI to AMBA 3 APB Bridge (BP135).
The component, when configured by another component such as the BP141_TZPC, permits control of secure access to up to 16 PrimeCell peripherals.
The PVBus makes no distinction between AXI and APB bus protocols. For simple models, you do not have to use a bridge peripheral when connecting devices to a processor.

BP135_AXI2APB - verification and testing
This component passes tests as part of an integrated platform.
BP135_AXI2APB - library dependencies
This component depends on the BP135TZSwitchControl component, which decodes the protection selection bits provided by the TZPROT ports and controls the protection routing of the embedded TZSwitch routing components.
