pragma SDS resource
Description
This pragma can be used at function call sites to manually specify resource binding.
Theresource
pragma is specified immediately preceding a call to a hardware function, directing the compiler to bind the caller to a specified accelerator instance. The SDSoC compiler identifies when multiple resource IDs have been specified for a function, and automatically generate a hardware accelerator and data motion network realizing the hardware functions in programmable logic.
Syntax
The syntax of the pragma is:
#pragma SDS resource( )
Where:
: Must 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 to functionmmult
will be bound to an accelerator with an ID of 1, and the second call tommult
will be bound to another accelerator with an ID of 2.
