1. A computer system comprising:
- a central processing unit (CPU);
at least one dedicated processing unit (DPU) coupled with said CPU via a network for transferring event descriptors to said CPU; and
an event controller including a representative-event queue and coupled with said CPU and DPU via said network, said event controller receiving said event descriptors transferred from said DPU to enter said event descriptors in said representative-event queue while selecting an order of entering said event descriptors, wherein said CPU receives consecutively said event descriptors from said representative-event queue.

Abstract
A computer system includes a central processing unit (CPU), a plurality of dedicated processing units (DPUs) for transferring therebetween event descriptors for allocating CPU processings to the DPUs. The computer system includes a plurality of event controllers each associated a corresponding one of the DPUs or CPU. The event controller receives the event descriptors issued by the DPUs and enters the event descriptors in a representative-vent queue in the order of the priority of the event descriptors.

10. A computer system comprising:
-
a central processing unit (CPU);
at least one dedicated processing unit (DPU) coupled with said CPU via a network for transmitting event descriptors to said CPU; and
an event controller coupled with said CPU and DPU via said network for receiving said event descriptors transferred from said DPU, to create a new event descriptor based on a plurality of said event descriptor and issue said new event descriptor to said CPU.

11. A method for receiving event descriptors issued from at least one dedicated processing unit (DPU) by a central processing unit (CPU) in a computer system, said method comprising the steps of:
-
receiving said event descriptors from said DPU in an event controller to enter said event descriptors in a representative-event queue by selecting an order of said event descriptors; and
consecutively receiving said event descriptors by said CPU from said representative-event queue. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
