System Description
MUSYCC also provides an on-device, 32-bit local expansion bus (EBUS) controller which allows a host processor
to access local memory and physical interface devices directly through MUSYCC over the PCI using configurable
memory mapping features.
MUSYCC manages buffer memory for each active data channel with common list-processing structures. The on-
device features allow data transmission between buffer memory and the serial interfaces with minimum host
processor intervention. This allows the host processor to concentrate on managing the higher layers of the protocol
stack.
