Line buffer unit for image processor

A method comprising:

• assigning, by a device having a plurality of line buffer interface units and a memory unit storing image data partitioned into a plurality of line groups, each line buffer interface unit to manage read and write requests for a respective line group of the plurality of line groups,
• receiving, by a particular line buffer interface unit of the plurality of line buffer interface units, a write request from a producer component of the device;
• identify, by the particular line buffer interface unit, a write location within the memory unit corresponding to the write request;
• storing, by the particular line buffer interface unit, data at the write location within the memory unit according to the write request;
• receiving, by the particular line buffer interface unit, a read request from one or more consumer components of the device;
• identifying, by the particular line buffer interface unit, a read location within the memory unit corresponding to the read request;
• providing, by the particular line buffer interface unit, data stored at the read location within the memory unit according to the read request;
• receiving, by the device, an indication that a line buffer interface unit has completed all outstanding read requests from one or more consumers components for a particular line group;
• and
• in response, reassigning, by the device, the line buffer interface unit to manage read and write requests for a different line group,
• wherein each line buffer interface unit has a dedicated programmable unit configuration space that is configured to store data representing properties of a line group to which the line buffer interface unit is assigned, and
• wherein reassigning the line buffer interface unit comprises updating, by the device, the data in the programmable unit configuration space of the line buffer interface unit to represent properties of the different line group.
