- Only supports asynchronous input RTPs from the host, marked as
"read-only."
- Synchronous RTPs, in/out RTPs, or output RTPs are not supported.
- The RTP memory in the master core is shared across neighboring slave cores.
- No locks (such as semaphore locks) are explicitly required from the user; the tool
automatically removes locks when sharing is enabled.
- In the graph code, the
initial_value constraint and update API can
only be applied to the master RTP port.
- You must manage updates explicitly and ensure a valid initial value before running
the graph, preventing garbage reads during initialization.
- Usage:
adf::share_parameter(master_rtp_port, {vector of
slave_rtp_ports}) to define shared RTPs.
- Checks performed to ensure correct usage include the following:
- Verify placement of master and slave RTP buffers to ensure shared memory
access between neighboring cores.
- An error occurs if sync RTPs, output RTPs, or in/out RTPs are used.
- Validate that master and slave RTPs have matching array sizes and data
types.
