Register pipe for multi-processing engine environment

A system of transferring data between a first processing engine and a second processing engine, said system comprising:

• means for establishing a register pipe between said first processing engine and said second processing engine, said means for establishing including means for mapping general purpose registers of said first processing engine to general purpose registers of said second processing engine to establish said register pipe;
• and
• means for transferring data between said first processing engine and said second processing engine using said register pipe, wherein data is transferred between said first and second processing engines without passing through memory.

A multi-processor computer system including a first processing engine and a second processing engine, said multiprocessor computer system comprising:

• a register pipe between said first processing engine and said second processing engine, said register pipe comprising at least one general purposes register in said first processing engine mapped to at least one general purpose register in said second processing engine;
• and
• wherein said first processing engine and said second processing engine are adapted to transfer data therebetween using said register pipe and without passing said data through memory of said multiprocessor computer system.

At least one program storage device readable by a machine, tangibly embodying at least one program of instructions executable by the machine to perform a method of transferring data between a first processing engine and a second processing engine, said method comprising:

• establishing a register pipe between said first processing engine and said second processing engine, said establishing including mapping general purpose registers of said first processing engine to general purpose registers of said second processing engine to establish said register pipe;
• and
• transferring data between said first processing engine and said second processing engine using said register pipe, wherein data is transferred between said first and second processing engines without passing through memory.
