Appeal No. 96-4169 Application 08/378,066 ISA computer. Raasch teaches that the peripheral controller enters a low power mode of operation while it awaits an interrupt from various devices, rather than actively polling these devices to determine which device or devices need service. In column 1, lines 53-58, Raasch teaches that in laptop computers in which power consumption is critical, it is important to consider any way to reduce the power consumption. In column 2, lines 6-14, Raasch discloses that conventional designs provide that the peripheral controller continuously polls various devices to determine if any data transferred from the keyboard is required. Power is unnecessarily consumed in these active polling processes. In column 2, lines 50-57, Raasch teaches that they have solved this unnecessary power consumption by utilizing memory mapped address decode architecture. In column 2, line 63, through column 3, line 4, Raasch discloses that their invention provides an interrupt controller for an interrupt driven peripheral controller for use in a host Industrial Standard Architecture compatible computer system, 8Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 NextLast modified: November 3, 2007
