Abstract

A computer system with an operating system and a data-processing system running on a host processor, and a receiver. The receiver sends interrupt signals to the operating system after the receiver has received data signals. The operating system establishes interrupt times and passes the interrupt signals to the data-processing system. The data-processing system accesses the data signals from the receiver and only partially processes the data signals during the interrupt times. The operating system also receives clock interrupt signals, which it passes on to the data-processing system. The data-processing system completes the processing of the data signals during the clock interrupt times that the operating system establishes in response to the clock interrupt signals.

Claims22

Dependent claims

A computer-implemented process for processing received signals, comprising the steps of:

(a) receiving data signals by a receiver;
(b) transmitting a data-received interrupt signal from the receiver to an operating system running on a host processor;
(c) establishing a data-received interrupt time by the operating system in response to the data-received interrupt signal;
(d) passing the data-received interrupt signal from the operating system to a data-processing system running on the host processor, wherein the data-received interrupt signal informs the data-processing system that the receiver has received the data signals;
(e) receiving the data signals by the data-processing system from the receiver during the data-received interrupt time;
(f) partially processing the data signals by the data-processing system during the data-received interrupt time;
(g) terminating the data-received interrupt time by the operating system;
(h) receiving a clock interrupt signal by the operating system;
(i) establishing a clock interrupt time by the operating system in response to the clock interrupt signal;
(j) passing the clock interrupt signal from the operating system to the data-processing system;
(k) completing the processing of the data signals by the data-processing system during the clock interrupt time;
and
(l) terminating the clock interrupt time by the operating system.
