Description

Load 2-component formatted data from a buffer surface, convert the data to packed 16 bit integral or floating point format, then store the result into a vector register. The instruction specifies the data format of the surface, overriding the resource descriptor.

Semantics

addr = CalcBufferAddr(VADDR.b32, SRSRC.b32, SOFFSET.b32, OFFSET.b32); VDATA[15 : 0].b16 = 16'B(ConvertFromFormat(MEM[addr + ChannelOffsetX()])); // Mem access size depends on format VDATA[31 : 16].b16 = 16'B(ConvertFromFormat(MEM[addr + ChannelOffsetY()]))
