Method apparatus for high-level programs with general control flow

A tangible, non-transitory, machine-readable medium, comprising machine-readable instructions, that when executed by one or more processors, cause the processor to:

• receive a high-level language representation to be implemented on an integrated circuit;
• after receiving the high-level language representation, generate one or more PHI nodes to implement at least a portion of the high-level language representation, wherein the one or more PHI nodes are configured to:
• receive a control signal indicating a source basic block responsible for branching to a basic block of the one or more PHI nodes, the source comprising a prior basic block at a first time and the source comprising the basic block at a second time;
• and
• based upon the control signal:
• at the first time, when the source comprises the prior basic block, providing an output according to a first rule;
• and
• at the second time, when the source comprises the basic block,
• providing the output according to a second rule.

A method, implemented via an integrated circuit, comprising:

• receiving one or more data signals;
• and
• processing the one or more data signals using one or more PHI nodes implemented on the integrated circuit, the one or more PHI nodes are configured to:
• receive a control signal indicating a source basic block responsible for branching to a basic block of the one or more PHI nodes, the source comprising a prior basic block at a first time and the source comprising the basic block at a second time;
• and
• based upon the control signal:
• at the first time, when the source comprises the prior basic block, providing an output according to a first rule;
• and
• at the second time, when the source comprises the basic block, providing the output according to a second rule.
