Methods and apparatus for creating and executing a packet of instructions organized according to data dependencies between adjacent instructions and utilizing networks based on adjacencies to transport data in response to execution of the instructions

A method and apparatus for creating and executing a packet of chained instructions in a processor. A first instruction specifies a first operand is to be accessed from a memory and delivered through a first path in a first network to a first output. A second instruction specifies the first operand is to be received from the first output, to operate on the first operand, and to generate a result delivered to a second output. The second instruction does not identify a source device for the first operand and a destination device for the result. A third instruction specifies the first result is to be received from the second output and delivered through a first path in a second network for storage in the memory. The first, second, and third instructions are paired together as a packet of chained instructions for execution by a processor.
