Section 10 SuperHyway Bus Bridge (SBR)
The SuperHyway bus bridge (SBR) performs access protocol conversion between the
SuperHyway (Shwy) bus and the SuperHyway bridge bus. At the same time, it also arbitrates
between the accesses to the SuperHyway bus by the three peripheral modules (SECURITY,
GETHER, and USBH) connected to the SuperHyway bridge bus.
10.1 Features
•
SuperHyway bus interface
Performs access protocol conversion between the SuperHyway bus and the SuperHyway
bridge bus.
•
Arbitration
The arbiter arbitrates between the accesses to the SuperHyway bus by the SECURITY,
GETHER, and USBH modules connected to the SuperHyway bridge bus. Priority can be set
for the individual modules or ports.
Figure 10.1 shows a block diagram of the SBR.
