Detailed Description

Innermost-first ND access pattern (d0..d3 / repeat), matching the convention used by verifyStridesWraps and NpuDmaMemcpyNdOp verification.

A runtime-sequence task BD may give more than kNdDmaDims dimensions, all of the ones past d2 iteration dimensions; decomposeNdDmaPattern reduces it to kNdDmaDims-dimension patterns.

baseOffset

int64_t xilinx::AIEX::NdDmaPattern::baseOffset = 0

Elements added to the address the offsets give.

Carries the position of a pattern peeled off the dimensions past kNdDmaDims, which no dimension of the peeled pattern can express.
