Abstract: A computer system and a method for transmitting interrupt messages through a parallel communication bus are provided. The computer system includes a first device operably communicating with a second device via a parallel communication bus. The first device is configured to transmit a first interrupt message through the parallel communication bus to the second device, wherein the first interrupt message has a data portion with a plurality of bits having a first identifier identifying the first device.

Abstract: A computer system and a method for queuing interrupt messages are provided. The computer system includes a parallel communication bus and a first device operably coupled to the parallel communication bus. The first device is configured to receive first and second interrupt messages transmitted through the parallel communication bus to a first bus address associated with the first device. The first and second interrupt messages each comprise a plurality of bits. The first device is configured to store the first and second interrupt messages in first and second memory locations, respectively, of a memory and to perform at least one task associated with the first interrupt message.
