Reducing energy and increasing speed by an instruction substituting subsequent instructions with specific function instruction

Apparatus for processing data comprising:

• data processing means for executing data processing operations specified by program instructions;
• and
• instruction decoder means for decoding program instructions to generate control signals for controlling said data means;
• wherein
• said instruction decoder means and said data processing means decode and execute a sequence of program instructions to evaluate a data processing function;
• said sequence of program instructions includes an intermediate value generating instruction, decoding of said intermediate value generating instruction by said instruction decoder means, and execution of said intermediate value generating instruction by said data processing means generating an intermediate value including an intermediate data value and an embedded opcode value;
• said sequence of program instructions includes, after said intermediate value generating instruction, an intermediate value consuming instruction for consuming said intermediate value;
• said instruction decoder means and said data processing means operate in dependence upon said embedded opcode value.

A method of processing data comprising the steps of:

• decoding and executing a sequence of program instructions to evaluate a data processing function, wherein
• said sequence of program instructions includes an intermediate value generating instruction, decoding and execution of said intermediate value generating an intermediate data value and an embedded opcode value;
• said sequence of program instructions includes, after said intermediate value generating instruction, an intermediate value consuming instruction for consuming said intermediate value;
• said steps of decoding and executing operate in dependence upon said embedded opcode.
