2.2.2.2 Multilayer AHB Interface
The Multilayer AHB specification [5] emerges with the aim of increasing the
overall bus bandwidth and provides a more flexible interconnect architecture
with respect to AMBA AHB. This is achieved by using a more complex inter-
connection matrix that enables parallel access paths between multiple masters
and slaves in a system.
Figure 2.3 shows a schematic view of the multilayer concept.
The multilayer bus architecture allows the interconnection of unmodified
standard AHB or AHB-Lite master and slave modules with an increased avail-
able bus bandwidth. The resulting architecture ...
