AHB-to-APB Bridge interfaces AHB and APB buses. It
is required to bridge the communication gap between low bandwidth peripherals on APB with the high bandwidth AHB.
Normally APB works without pipelining of address. The bridge is used to control the AHB such that it can halt for a particular number of cycles and synchronization is maintained. This is to ensure that there is no data loss between AHB to APB or APB to AHB data transfers....view full
This interface fills the gap between APB bridge
and APB slaves by one common interface, which is compatible with most of the APB slaves. Using this interface, theAHB-to-APB bridge can be connected directly to the compatible slave interface.
The APB-to-slave interface converts APB bridge signals to peripheral equivalent signals. Normally the peripheral has different interface compared to APB signals....view full
