ARM920T Core and Advanced High-Speed Bus (AHB)
EP93xx User’s Guide
Before an AMBA-to-AHB transfer can commence, the bus master must be granted access to
the bus. This process is started by the master asserting a request signal to the Arbiter. The
Arbiter then indicates when the master will be granted use of the bus. A granted bus master
starts an AMBA-to-AHB transfer by driving the address and control signals. These signals
provide information on the address, direction and width of the transfer, as well as indicating
whether the transfer is part of a burst.
Two different forms of burst transfers are allowed:
• Incrementing bursts, which do not wrap at address boundaries
• Wrapping bursts, which wrap at particular address boundaries.
