29.5. Generic Crosspoint IP Software API

The IP includes software for run-time control. The IP does not fit any of the generic device models provided by the Nios II HAL and it exposes a set of dedicated accessors to the control and status registers. The IP driver structure inherits the base driver structure so all common methods defined in Video and Vision Processing IPs Software API are applicable.
Table 472.  Generic Crosspoint IP Software API
Name Description
intel_vvp_generic_crosspoint_init Initialize a Generic Crosspoint instance
intel_vvp_generic_crosspoint_get_output Get an output's selected input port
intel_vvp_generic_crosspoint_set_output Set an output's selected input port

intel_vvp_generic_crosspoint_init

prototype:
 int intel_vvp_generic_crosspoint_init(intel_vvp_generic_crosspoint_instance* instance, intel_vvp_core_base base);
description:

Initialization function for a VVP Generic Crosspoint instance.

Attempts to initialize the fields of the Generic Crosspoint and its base core

argument:

instance, pointer to the intel_vvp_generic_crosspoint_instance to initialize

base, the accessor for the core (on Nios this is a pointer to the base address of the core)

return value:

kIntelVvpCoreOk success

kIntelVvpCoreVidErr if the vendor id of the core is not the IntelFPGA vendor ID.

kIntelVvpCorePidErr if the product id of the core is not the Generic Crosspoint product id

kIntelVvpCoreInstanceErr if the instance parameter is zero (null pointer)

intel_vvp_generic_crosspoint_get_output

prototype:
 uint8_t intel_vvp_generic_crosspoint_get_output(intel_vvp_generic_crosspoint_instance* instance, uint8_t output);
description:

Get an output's selected input port

argument:

instance, pointer to the intel_vvp_generic_crosspoint_instance

output, number of the output port

return value:

Number of the input port selected by the output port

intel_vvp_generic_crosspoint_set_output

prototype:
 int intel_vvp_generic_crosspoint_set_output(intel_vvp_generic_crosspoint_instance* instance, uint8_t output, uint8_t input);
description:
argument:

instance, pointer to the intel_vvp_generic_crosspoint_instance

output, number of the output port

input, number of the input port to select

return value:

kIntelVvpGenericCrosspointOk success

kIntelVvpGenericCrosspointInstanceErr if the instance number is zero (null pointer)

kIntelVvpGenericCrosspointInputErr if the selected input doesn't exist

kIntelVvpGenericCrosspointOutputErr if the selected output doesn't exist
