pub struct AffinePrefetchOperation<'c> { /* private fields */ }
Expand description
A prefetch
operation. Affine prefetch operation.
The affine.prefetch
op prefetches data from a memref location described
with an affine subscript similar to affine.load, and has three attributes:
a read/write specifier, a locality hint, and a cache type specifier as shown
below:
affine.prefetch %0[%i, %j + 5], read, locality<3>, data : memref<400x400xi32>
The read/write specifier is either ‘read’ or ‘write’, the locality hint specifier ranges from locality<0> (no locality) to locality<3> (extremely local keep in cache). The cache type specifier is either ‘data’ or ‘instr’ and specifies whether the prefetch is performed on data cache or on instruction cache.
