Abstract: Techniques are disclosed relating to processor communications fabrics. In some embodiments, a processor includes multiple client circuitry and fabric circuitry that includes at least first and second instances of a tile. The tile may include: client inputs configured to interface with client circuits, tile inputs configured to interface with one or more other tile instances, and communication resources assignable to the client inputs and tile inputs. The communications resources may include: multiple internal links, client outputs configured to interface with client circuits, and tile outputs configured to interface with one or more other tile instances. Control circuitry may, in a given cycle, assign communication resources of a given tile instance to at least a portion of the client inputs and tile inputs for a next cycle, based on priority information. The control circuitry may update priority information based on assignment results over multiple cycles.

Abstract: A layer of a liquid composition containing a residue that is polymerizable on contact with a gaseous polymerizing agent and a photocurable residue, which residues may be on the same or different molecules, is contained with a gaseous polymerizing agent so that the layer solidifies but remains photocurable. Subsequently the solidified layer is exposed to actinic radiation in a predetermined pattern and those parts of the layer that are not photocured are removed by treatment with a suitable solvent.Typical polymerizable residues include cyanoacrylates that polymerize on exposure to water vapor, ammonia, or an amine. Typical photocurable residues include acrylates, and methacrylates.The process is suitable for the manufacture of printing plates and printed circuits.

Abstract: A polymerizing agent is applied to a substrate followed by a layer of a liquid composition containing both a polymerizable residue and a photocurable residue. The polymerizable residue is polymerized by the polymerizing agent first applied so that the layer solidifies but remains photocurable. Subsequently this solidified layer is exposed to actinic radiation in a predetermined pattern and those parts of the layer that are not photocured are removed by treatment with a suitable solvent.Typical polymerizable residues include cyanoacrylates, the polymerizing agents for which may be water, ammonium hydroxide solution, an alkali metal hydroxide solution, or an amine. Typical photocurable residues include acrylates and methacrylates.The process is suitable for the manufacture of printing plates and printed circuits.

Abstract: A layer of a liquid composition containing(A) a heat-activated latent polymerizing agent for 1,2-epoxides with(B) a light-sensitive compound having in the same molecule at least one 1,2-epoxide group and at least one chalcone or cinnamate group, or with a mixture of(C) a compound containing at least one 1,2-epoxide group together with(D) a compound containing at least one chalcone or cinnamate group,is heated so that the layer solidifies due to thermal polymerization through the 1,2-epoxide group, remaining, however, photocrosslinkable. The solidified layer is exposed in a predetermined pattern to actinic radiation, the parts so exposed becoming photocrosslinked through the chalcone or cinnamate unit(s) and hence insoluble. An image is produced which can be developed by means of suitable solvents.An example of a suitable latent polymerizing agent (A) is boron trichloride-N-methylpiperidine complex, and a suitable light-sensitive compound (B) is 1-(p-(glycidyloxy)phenyl)-5-phenylpenta-1,4-dien-3-one.

Abstract: Images are prepared by a process in which a layer, supported on a substrate, of a liquid composition comprising(a) an anaerobically polymerizable material and(b) a photopolymerizable material is maintained in a substantially oxygen-free environment such that the composition solidifies. It is then exposed imagewise to actinic radiation and treated with a developer to remove parts of the layer which have not been struck by the radiation.The anaerobically polymerizable and photopolymerizable materials may be a mixture of two or more materials having these different functions, such as an acrylate ester with an azido compound, or the two functions may be combined in a single molecule. The products are suitable for use in producing printing plates and printed circuits.
