12.2.12. MONO_SRC_COPY_IMMEDIATE_BLT

This instruction allows the driver to send data through the instruction stream which eliminates the read latency of reading a source from memory. If an operand is in system cacheable memory and is either small or only accessed once, it can be copied directly to the instruction stream versus to graphics accessible memory.

The IMMEDIATE_BLT data MUST transfer an even number of DWs. The BLT engine will hang if it does not get an even number of DWs or the exact number of QWs required.

This BLT instruction performs a monochrome source copy where the only operands involved are a monochrome source and destination. The source and destination operands cannot overlap, which means that the X direction must always be forward.

Monochrome source data is sent through the instruction stream. BR11 = DW0[15:0] - 4

All non-text monochrome sources are word aligned. At the end of a scan line the monochrome source, the bits until the next word boundary must be ignored. The Monochrome source data bit position field [2:0] indicates which bit position within the first byte should be used as the first source pixel.

The monochrome source transparency mode indicates whether to use the source background color or deassert the write enables when the bit in the source is 0. When the source bit is 1, then the source foreground color is used in the ROP operation. The ROP value chosen should involve the Mono source data in the ROP operation.

The Destination pitch can either be positive or negative to allow mirroring in the Y direction.
