Method and apparatus for coordinating cooperating resources and its application

A method comprising:

• storing a first and a second control value in a first and a second current write storage location of a first and a second first in, first out storage structure (FIFO) respectively, when a first resource is assigned a first task;
• storing the second and the first control value in a third and a fourth current write storage location of the first and the second FIFO respectively, when a second resource is assigned a second task;
• removing the first and the second control value in a first and a second current read storage location of the first and the second FIFO respectively, when the first resource outputs a first result of the first task;
• and
• removing the second and the first control value in a third and a fourth current read storage location of the first and the second FIFO respectively, when the second resource outputs a second result of the second task.

A method comprising:

• removing a first and a second control value in a first and a second current read storage location of a first and a second first in, first out storage structure (FIFO) respectively, when a first resource outputs a first result of a first task;
• removing the second and the first control value in a third and a fourth current read storage location of the first and the second FIFO respectively, when a second resource outputs a second result of a second task;
• said first resource arbitrating for a bus to output said first result, when the first current read storage location of the first FIFO contains said first control value;
• and
• said second resource arbitrating for the bus to output said second result, when the third current read storage location of the second FIFO contains said first control value.

An apparatus comprising:

• a first in, first out storage structure (FIFO) to associate with one of multiple system resources, to store results of tasks completed by the one resource;
• and
• a control logic coupled with the FIFO to:
• store a control value in a current write memory location of the FIFO when any of the multiple system resources receives a task to be completed, the control value assigned a logic state of true if the resource that received a task is the one resource associated with the FIFO, and otherwise assigned a logic state of false, and
• access a current read memory location of the FIFO when any of the multiple parallel system resources indicates that a task is completed, and indicate to the FIFO to output the stored task result if the control value read from the current read memory location is a logic state of true.

A system comprising:

• multiple resources operating in parallel to receive and execute tasks;
• multiple first in, first out storage cells (FIFO), each corresponding separately to one of the multiple resources, to store results of the executed tasks;
• and
• multiple control logic units, each coupled with one of the FIFOs, to write to a current write location of the respective FIFOs a control value of logic state true if the resource corresponding to the control logic unit receives a task, and a control value of logic state false if a resource not corresponding to the control logic unit receives a task, and to read a current read location of the respective FIFOs when one of the resources completes execution of a task, and indicate to the respective FIFOs to output the stored results of the executed tasks when a control value of logic state true is read from the current read location of the respective FIFOs.
