30 Communication Architectures for SoC
• CoreLink Advanced Quality of Service, is an option for the CoreLink
TM
Network Interconnect product, and gives the SoC architect the essential
tools to efficiently share the finite bandwidth of critical interfaces like
Double Data Rate (DDR) memory. It performs traffic shaping to mini-
mize average latency (best effort masters) or guarantee bandwidth and
latency for real-time traffic.
2.2.5.2 ARM’s CoreSight
For on-chip debug and trace, ARM has defined the openCoreSight Architec-
ture to allow SoC designers to add debug and trace capabilities for other IP
cores into the CoreSight infrastructure. ARM
