Abstract: Delivering immediate values by using program counter (PC)-relative load instructions to fetch literal data in processor-based devices is disclosed. In this regard, a processing element (PE) of a processor-based device provides an execution pipeline circuit that comprises an instruction processing portion and a data access portion. Using a literal data access logic circuit, the PE detects a PC-relative load instruction within a fetch window that includes multiple fetched instructions. The PE determines that the PC-relative load instruction can be serviced using literal data that is available to the instruction processing portion of the execution pipeline circuit (e.g., located within the fetch window containing the PC-relative load instruction, or stored in a literal pool buffer), The PE then retrieves the literal data within the instruction processing portion of the execution pipeline circuit, and executes the PC-relative load instruction using the literal data.

Abstract: Operand-based reach explicit dataflow processors, and related methods and computer-readable media are disclosed. The operand-based reach explicit dataflow processors support execution of a producer instruction that explicitly names a target consumer operand of a consumer instruction in a consumer operand encoding namespace of the producer instruction. The produced value from execution of the producer instruction is provided or otherwise made available as an input to the named target consumer operand of the consumer instruction as a result of processing the producer instruction. The target consumer operand is encoded in the producer instruction as an operand target distance relative to the producer instruction. Instructions in an instruction stream between the producer instruction and the targeted consumer instruction that have no operands do not consume an operand reach namespace in the producer instructions. This provides for a deeper explicit consumer naming reach for a given bit size of the operand reach namespace.
