International Classification:

G06F 954

US Classification:

709321, 709318

Abstract:

A computer system in accordance with the present invention provides a method of communicating asynchronous events from a mini-port driver of a computer system to a software component without polling the mini-port driver. The computer system provides a monolithic driver as a dispatch between a mini-port driver and a software component. Until an asynchronous event is detected, an event thread in the monolithic driver to a software component is blocked. When an asynchronous event is detected by the mini-port driver, the mini-port driver calls the monolithic driver with a monolithic driver entry point which queues the event and unblocks the event thread. The monolithic driver provides the asynchronous event to the software component through the unblocked event thread. The event thread is then re-blocked and remains blocked until another asynchronous event is detected. Asynchronous events are thereby communicated from a mini-port driver to a software component without polling the mini-port driver.

International Classification:

G11C 1908

US Classification:

365 5

Abstract:

A set of three input, three output bubble logic gates forms all of the possible distinct output functions for conservative three variable gates. The magnetic interaction between single wall domains propagating through separate channels defined by closely spaced circuit element paths causes the domains to switch to or remain on alternate paths via between-path transfer means in a predetermined fashion. In addition to vertically graded element transfer means, several new circuit arrangements are introduced including non-graded elements, strong and weak S-curves, elements having uneven gradation, and other circuit techniques. A group of primitive realizations are described which can be combined to produce other gates having output functions in each of 31 equivalence classes. A methodology for using the gates in logic design is suggested, and several new building block gates producing functions of two variables are presented.

Abstract:

Magnetic bubble logic circuits performing the functions of various forms of flip-flops and decoders are presented. Set-reset and trigger flip-flops are constructed from specialized 3--3 conservative bubble logic circuits. Two forms of tree-type decoders employing crossovers of bubble tracks are illustrated for generating all possible product permutations of a plurality of input variables. Planar decoders and cross point circuits without crossovers are combined in matrix form to provide a multi-variable decoder without internal crossovers.
