One memory tile size is limited to 512 KB. However, the DMA channels
0~3 can access the neighboring east and west
memory tiles. The tool supports using shared buffer up to 1 MB.
To use shared buffer up to 1 MB, constrain the location of the shared buffer in
the graph code. For
example:
shared_buffer<int32> mtxA;
......
// 262144 int32 input in elements, input port=1, output port=1
mtxA = shared_buffer<int32>::create({262144}, 1, 1);
//constrain the starting address of the shared buffer to 0x0 of memtile(7,0)
location<buffer>(mtxA)=address(7,0,0x0);
