Processing core with metadata actuated conditional graph execution

A computer-implemented method for a conditional execution of a directed graph comprising:

• evaluating a set of output data from an execution engine;
• generating metadata for a first data tile based on the evaluating of the set of output data;
• storing, subsequent to the evaluating of the set of output data, a first data tile in a random access memory, wherein the set of output data is stored as a first set of data elements in the first data tile, wherein the first data tile includes a header, and wherein the metadata is stored in the header in the random access memory;
• storing a second data tile in the random access memory, wherein the second data tile includes a second set of data elements;
• fetching, subsequent to the storing of the first data tile and metadata in the random access memory, an instruction, for execution by the execution engine, wherein execution of the instruction requires an arithmetic logic operation using:
• (i) an arithmetic logic unit;
• (ii) a first data element in the first set of data elements;
• and (iii) a second data element in the second set of data elements;
• evaluating the metadata from the header;
• and
• conditionally executing the arithmetic logic operation based on the evaluating of the metadata;
• wherein a conditionally executed output of the arithmetic logic unit resulting from the conditional execution of the arithmetic logic operation is not equal to a standard output of the arithmetic logic unit resulting from a standard execution of the arithmetic logic operation.
