-aie-create-cores
Create CoreOp, MemOp, and FlowOp of AIE dialect
Lower toplevel ‘call’ operations with implicit data movement into aie.core, aie.mem, and aie.flow operations with explicit data movement. The tile tile associated with the operations is inferred based on the aie.x and aie.y attributes of the call operation. e.g.:
func.func @aie_task(%arg0: memref<256xi32>, %arg1: i32) -> () {
...
return
}
%a = constant 0 : i32
func.call @aie_task(%buf, %a) { aie.x = 1, aie.y = 1 } : (memref<256xi32>, i32) -> ()
will result in:
%0 = AIE.tile(1, 1)
%1 = AIE.buffer(%0) : memref<256xi32>
%2 = AIE.buffer(%0) : memref<1xi32>
%c0_i32 = constant 0 : i32
%5 = AIE.core(%0) {
...
}
In this case, each argument to aie_task results in an explicit buffer accessed by the core.
-aie-create-locks
Generate physical lock ops from logical lock (token) ops
Tokens represent high-level buffer synchronization through a sequence of pipeline stages. This pass lowers token operations into physical aie.lock operations.
-aie-dma-to-ipu
-aie-herd-routing
Lowering herds with place and route ops to AIE cores, mems, and switchboxes
An experimental pass which elaborates herd operations (e.g. aie.herd, aie.iter, aie.select) into an explicit representation (e.g. aie.core, aie.mem, etc.).
-aie-lower-broadcast-packet
Replace combination of broadcast and packet-switch by packet-flow
Replace combination of broadcast and packet-switch by packet-flow
-aie-lower-memcpy
Lower aie.memcpy operations to Flows and DMA programs
aie.memcpy operations are an experimental high-level abstraction which move data from one buffer to another. This pass lowers them into appropriate aie.flow and aie.mem operations.
-aie-lower-multicast
Lower AIE.multicast operation to AIE.flow operations
This pass replaces AIE.multicast operation with the equivalent number of AIE.flow operations. The lowered AIE.flow operations have the same source port but different destinations.
-aiex-standard-lowering
Lower AIEX operations
AIEX Ipu Ops are removed.
