CoreAHB2APB

• Supplied in SysBASIC Core Bundle

• Up to 16 APB Slave Devices Supported
• Automatic Connection to CoreAHB and CoreAPB in CoreConsole

CoreAHB2APB (AMBA Bridge) is an AHB slave that links the AHB bus to the APB bus and acts as the Master on the APB bus. Address decoding for the APB bus is carried out within CoreAHB2APB, and this provides select signals for up to 16 APB slave slots.

Read and write transfers on the AHB bus are converted to corresponding transfers on the APB bus. CoreAHB2APB Highbandwidth peripherals, such as memory controllers, are typically connected to the AHB, whereas the APB bus is used for less demanding peripherals, such as watchdogs. Unlike the AHB bus, transfers on the APB bus are not pipelined.
