Specifying Resource Binding

This pragma can be used for function callsites to manually specify resource binding.

The syntax of the pragma is:

#pragma SDS resource(ID)

Theresourcepragma is specified immediately preceding a call to a hardware function, directing the compiler to bind the caller to a specified accelerator instance.

TheIDmust be a compile time unsigned integer constant. For the same function, each unique ID represents a unique instance of the hardware accelerator.

Example 1

The following code snippet shows an example of using this pragma with a different ID:

{ #pragma SDS resource(1) mmult(A, B, C); #pragma SDS resource(2) mmult(D, E, F); ... }

In the above example, the first call tommultwill be bound to an accelerator with an ID of 1, and the second call tommultwill be bound to another accelerator with an ID of 2.
