Function Documentation

◆ computeStrideInBytes()

Value computeStrideInBytes ( Location loc,
MemRefType mType,
Value elementStride,
RewriterBase & rewriter )
static

Returns stride expressed in number of bytes for the given elementStride stride encoded in number of elements of the type mType.

◆ getTileSizes()

SmallVector< Value > getTileSizes ( Location loc,
amx::TileType tType,
RewriterBase & rewriter )
static

Maps the 2-dim vector shape to the two 16-bit tile sizes.

The first dimension directly translates into the number of rows of the tiles. The second dimensions needs to be scaled by the number of bytes.

◆ inferStride()

Value inferStride ( Location loc,
MemRefType mType,
Value base,
RewriterBase & rewriter )
static

Maps the 2-dim memref shape to the 64-bit stride.

Note that the buffer shape may "envelop" the actual tile shape, and may be dynamically sized.

◆ verifyMultShape()

LogicalResult verifyMultShape ( Operation * op,
