Abstract: There is disclosed a data processor having a clustered architecture that comprises at least one branching cluster, at least one non-branching cluster and remote conditional branching control circuitry. Each of the clusters is capable of computing branch conditions, though only the branching cluster is operable to perform branch address computations. The remote conditional branching control circuitry, which is associated with each of the clusters, is operable in response to sensing a conditional branch instruction in a non-branching cluster to (i) cause the branching cluster to compute a branch address and a next program counter address, (ii) cause the non-branching cluster to compute a branch condition, and (iii) communicate the computed branch condition from the non-branching cluster to the branching cluster. The data processor then uses the computed branch condition to select one of the branch address or the next program counter address.

Abstract: A process for bonding two distinct substrates that integrate microsystems, including the steps of forming micro-integrated devices in at least one of two substrates using micro-electronic processing techniques and bonding the substrates. Bonding is performed by forming on a first substrate bonding regions of deformable material and pressing the substrates one against another so as to deform the bonding regions and to cause them to react chemically with the second substrate. The bonding regions are preferably formed by a thick layer of a material chosen from among aluminum, copper and nickel, covered by a thin layer of a material chosen from between palladium and platinum. Spacing regions ensure exact spacing between the two wafers.

Abstract: Inquiry data received from sequential target devices is stored in a cache memory. In one embodiment, the cache memory is coupled to a router. In one embodiment, when the router receives from a host an inquiry command about a target, the router first checks to see if the inquiry command can be serviced from the cache. If so, the inquiry data about the target is retrieved from the cache and returned to the host. If not, the router checks to see if the target is busy. If not busy, the router routes the inquiry command to the target and stores the inquiry data returned by the target in the cache. If the target is busy, the router places the inquiry command in a queue. When the target becomes available, the router forwards the inquiry command to the target for processing, thereby keeping the inquiry command from timing out.

Abstract: Systems and methods are disclosed for interaction between different cache coherency protocols. One system may comprise a home node that receives a request for data from a first node in a first cache coherency protocol. A second node provides a conflict response to a request for the data from the home node. The conflict response indicates that an ordering point for the data is migrating according to a second cache coherency protocol, which is different from the first cache coherency protocol.

Abstract: Oxo anions (both singly and multiply charged), such as phosphates, polyphosphates, and phosphate esters, serve as additives, and in the case of cationic dyes, may serve as replacement counter-ions, for use in thermal ink-jet inks to reduce kogation significantly. The addition of such additive essentially eliminates kogation for the life of ink pens. Further, such additives will prevent kogation for inks containing dyes with negatively-charged water-solubilizing groups, such as sulfonate and carboxylate.
