Description

The BRC3 LP-Serial Endpoint Core implements a
complete RapidIO endpoint core capable of supporting
link rates of up to 12.5 Gbps per lane. It includes shared
memory and messaging logical layer functions. It also
includes functions that allow the endpoint to be managed with or without a local processor. Figure 1 illustrates the overall architecture of the core.


The core integrates an IO Logical Layer Initiator
block that maps AXI4 transactions into RapidIO IO
Logical request packets. The IO Logical Layer Target
block maps RapidIO IO Logical request packets into
AXI4 transactions on the user interface. Together these
functions support the transparent, low latency sharing
of memory across the link.


The HARSH profile support provide a range of
features that support the creation of high availability
systems. This includes MECS timestamp synchronization
that coordinates timing functions across the system
with nano-second accuracy. The error management
functions provide detailed traceability of system level
errors along with optional error timestamping to assist
with error analysis.
