43.5. Video Frame Buffer IP Software API

The IP has a software driver for software control of the IP at run time. The IP does not fit any of the generic device models provided by the Nios II HAL. It exposes a set of dedicated accessors to the control and status registers. The driver structure inherits the base driver structure so all common methods described in Video and Vision Processing IPs Software API are applicable.

Register definition header file: intel_vvp_vfb_regs.h

Include file: intel_vvp_vfb.h

Table 776.  Video Frame Buffer IP API Reference
Name Description
intel_vvp_vfb_init Initialize the Frame Buffer instance.
Intel_vvp_core_* .Accessors defined in Video and Vision Processing IPs Software Programming Model . Writable when Lite is on. Readable when Lite is off and Debug features is on.
