The AHB to APB Bridge translates an AHB bus transaction (read or write) to an APB bus transaction.  This is accomplished via two small state machines - one on the HCLK domain and another on the PCLK domain.

The AHB to APB Bridge acts as an AHB Slave, and an APB Master in an AHB/APB subsystem.  Typically, the AHB to APB Bridge has its AHB interface connected to a Slave port on an AHB Channel module, and its APB interface connected to the Master port on an APB Channel module.
