int XVprocSs_BuildRoutingTable ( XVprocSs * XVprocSsPtr )

#include <xvprocss_router.c>

This function examines the subsystem Input/Output Stream configuration and builds a routing table for the supported use-case.

The computed routing table is stored in the scratch pad memory

Parameters

XVprocSsPtr is a pointer to the Subsystem instance to be worked on.

Returns: XST_SUCCESS if routing table can be created else XST_FAILURE

XVprocSs_Config* XVprocSs_LookupConfig ( u32 DeviceId )

#include <xvprocss_sinit.c>

This function looks for the device configuration based on the unique device ID.

The table XVprocSs_ConfigTable[] contains the configuration information for each instance of the device in the system.

Parameters

DeviceId is the unique device ID of the device being looked up

Returns: A pointer to the configuration table entry corresponding to the given device ID, or NULL if no match is found

void XVprocSs_ProgRouterMux ( XVprocSs * XVprocSsPtr )

#include <xvprocss_router.c>

This function traverses the computed routing table and sets up the AXIS switch registers, to route the stream through processing cores, in the order defined in the routing map.

Parameters

XVprocSsPtr is a pointer to the Subsystem instance to be worked on.

Returns: None

void XVprocSs_SetupRouterDataFlow ( XVprocSs * XVprocSsPtr )

#include <xvprocss_router.c>

This function traverses the routing map built earlier and configures each sub-core in the processing path per its location in the chain.

Each core in the processing path is marked and only marked cores are started All remaining cores stay disabled

Parameters

XVprocSsPtr is a pointer to the Subsystem instance to be worked on.

Returns: None
