Abstract

PC'er hvor det er mulig å tilbakestille og initialisere og Isolere den vanlige systemctyreprosessoren dersom en vekslende systemstyrer er anordnet for systemet. For dette formålet Innbefatter et PC-system en høyhastlg- hets lokalprosessordatabuss, en inngang/utgangdata- buss, en mikroprosessor koblet direkte med lokalproses- sorbussen, en kontakt koblet direkte med lokalproses- sorbussen for å tilpasse og motta en vekslende prosessor og en bussgrensesnittstyrer koblet direkte til lokalprosessorbussen og direkte med inngang/utgang- databussen for å tilveiebringe kommunikasjoner mellom lokalprosessorbussene og inngang/utgangdatabussen. Bussgrensesnittstyreren sørger for detekterlng av tilstedeværelsen av en vekslende prosessor anordnet i kontakten og som reaksjon på detekteringen av tilstede- værelsen av en vekslende prosessor foretas overføring av styring av lokalprosessorbussen fra mikroprosessoren til en vekslende prosessor.
