with that region you are writing to four slices and not one. also you may try working with simple 2D image first. also what exactly doesn't work?
View ArticleRe: VLIW 5 Architecture processing element
there are 16 processing elements in one CU. the 4/5 ALU are executing vectorized operations from same work item. so if you write float4 a,b,c; c=a+b; it will execute with single VLIW instruction. on...
