Abstract
The present invention relates generally to a method for improving the throughput of data transfers on a bus. More specifically, data setup and hold times relative to REQ# and ACK# signal edges are adjusted programmatically to provide greater integrity in the transmission of data.
Claims21
A method of improving communication on a SCSI bus, the method comprising the steps of:
- providing a SCSI data signal;
- providing a SCSI clock signal having a setup time relative to the SCSI data signal;
- and
- adjusting the setup time on a device-by-device basis.
A method of improving communication on a SCSI bus, the method comprising the steps of:
- providing a SCSI data signal;
- providing a SCSI clock signal having a setup time relative to the SCSI data signal;
- and
- adjusting the setup time, wherein the setup time is adjusted by +18.7 nanoseconds to −12.5 nanoseconds.
A SCSI repeater circuit, the repeater circuit comprising:
- logic for providing a SCSI data signal on a SCSI bus,
- logic for providing a SCSI clock signal having a setup time relative to the SCSI data signal;
- and
- logic for adjusting the setup time on a device-by-device basis.
A SCSI repeater circuit, the repeater circuit comprising:
- logic for providing a SCSI data signal on a SCSI bus;
- logic for providing a SCSI clock signal having a setup time relative to the SCSI data signal;
- and
- logic for adjusting the setup time, wherein the setup time is adjusted by +18.7 nanoseconds to −12.5 nanoseconds.
A SCSI controller, the controller comprising:
- logic for providing a SCSI data signal on a SCSI bus;
- logic for providing a SCSI clock signal having a setup time relative to the SCSI data signal;
- and
- logic for adjusting the setup time on a device-by-device basis.
A SCSI controller, the controller comprising:
- logic for providing a SCSI data signal on a SCSI bus;
- logic for providing a SCSI clock signal having a setup time relative to the SCSI data signal;
- and
- logic for adjusting the setup time, wherein the setup time is adjusted by +18.7 ns to −12.5 ns.
