Preliminary data sheet
Table 8: Resource ID Assignment
The location of a layer in the overall QVCP address map is shown in
Table 9: Register Space Allocation
Each functional unit which belongs to a layer occupies a fixed spot within the layer
address range of 0x200H bytes. However the layer assignment of this functional unit
is programmable. It should usually follow the pixel data flow for a specific image
surface through the functional units involved.
Two 32-bit registers, RESOURCE_ID and FU_ASSIGNMENT, are used to assign all
resources to a specific layer address space. One is used to identify the resource to be
assigned. The other register is split up into 4-bit chunks which contain the specific
assignment for the resource identified in the first register. This allows for up to 8
resources of the same kind per functional unit. In this specific QVCP implementation
only a maximum of two of the same kind of each resource is needed for non-pool
resources and only one location is needed for the pooled resource. The remaining
slots are reserved for future implementations. The two registers act as access points
to an internal table which keeps the programmed values. All resources are
programmed through the same two registers. The ID register has to be written first.
