2.2.8.2 SDRAM Slave Arbiter
2.2.8.3 EBI Bus Arbiter
2.3.1 AHB Slave
2.3 AHB Decoder
The SDRAM Slave Arbiter prioritizes between accesses from the AHB bus and the Raster
DMA bus. If an access request from the AHB arrives at the same time as an access request
from the Raster DMA, the Raster DMA will be given access while the AHB request is queued.
The EBI Bus Arbiter is used to arbitrate between accesses from the SDRAM controller and
the Static Memory controller, where priority is given to accesses from the SDRAM controller.
The AHB Decoder contains the device memory map for all of the AHB masters/slaves and for
the APB bridge. When a particular address range is selected, the appropriate signal is
generated as defined in
(For additional information, see 17,
An AHB Slave responds to transfers initiated by bus masters. The slave uses signals from
the decoder to determine when it should respond to a bus transfer. All other signals required
for the transfer, such as the address and control information, are generated by the bus
master.
Note: Due to decoding optimization, the AHB peripheral registers are aliased throughout each
peripherals register bank. Do not attempt to access an unspecified register within the
bank.
