<p>Access to bus devices on a bus is granted in a computer system, with each bus device asserting a request signal to request the bus. A detector determines if a bus device is multi-threaded or single-threaded. An arbiter masks or does not mask the request signal of a retried bus device based on whether the bus device is a multi-threaded device. The arbiter masks the request signal of a retried bus device if it is a single-threaded device, but does not mask the request signal if the retried bus device is a multi-threaded device. The bus device request includes a delayed request transaction, and the bus includes a PCI bus.</p> |
