Processor with automatic scheduling of operations

A method of operating a processor to execute a plurality of instructions, each instruction having at least a first and a last operand associated therewith, the method comprising:

• a) loading a memory structure with the plurality of instructions;
• b) applying a plurality of operands to a functional unit based on a first instruction of the plurality of instructions to generate a result;
• c) identifying a second instruction having at least a first and a last operand to be associated therewith and requiring the result as an operand;
• d) when the result is the first operand to be associated with the second instruction, storing the result in a memory structure in a first memory location and associating the first memory location with the second instruction;
• and
• e) when the result is the last operand to be associated with the second instruction, storing the result in a second memory location in a memory structure and associating the first memory location with the second memory location.

A method of operating a processor of the type having:

• (i) functional logic having inputs, the functional logic producing a result based on operands applied to the inputs;
• (ii) operand storage memory;
• (iii) an instruction store;
• and (iv) a transfer memory, the method comprising:
• a) loading into the instruction store a plurality of instructions having a first tag associated therewith, each instruction representative of an expression and containing an indication of a subsequent instruction that uses the result produced upon evaluation of the expression as an operand;
• b) evaluating, with the functional logic, an expression based on a first instruction in the instruction store to generate a first result;
• c) using the indication of a subsequent instruction loaded into the instruction store as part of the first instruction to select a destination for the result, wherein:
• i) the destination is at least one of the operand storage memory, the transfer memory and an input of the functional logic;
• and
• ii) the indication of the subsequent expression includes a subsequent expression tag and selecting a destination comprises selecting a destination in part based on the tag for the subsequent expression and the first tag.
