In a multi-processor system with a high degree of inter processor communication, an operating system extension is described as a kernel function to poll a receive buffer. This is an opportunistic poll that continues to run in the user context after an application process has invoked the kernel with a blocking receive function. It is also running whenever no higher priority task is running. New data packets may be received for the present user application process while avoiding context switches, and for a different user process while avoiding interrupts. A hardware implemented delay timer and a buffer fill monitor generate interrupts when the system is not polling, thus guaranteeing a maximum latency and preventing buffer overflow, but these interrupts are largely avoided by polling when the system is handling a large amount of inter processor data traffic.
A method for operating a computer, the computer having a multi-tasking operating system that includes a user space and a kernel in a kernel space, a receive buffer and a plurality of application processes, each of the plurality of application processes including a user application that runs in the user space, the method comprising the steps of:
