Abstract: A hierarchical memory request stream arbitration technique merges coherent memory request streams from multiple memory request sources and arbitrates the merged coherent memory request stream with requests from a non-coherent memory request stream. In at least one embodiment of the invention, a method of generating a merged memory request stream from a plurality of memory request streams includes merging coherent memory requests into a first serial memory request stream. The method includes selecting, by a memory controller circuit, a memory request for placement in the merged memory request stream from at least the first serial memory request stream and a merged non-coherent request stream. The merged non-coherent memory request stream is based on an indicator of a previous memory request selected for placement in the merged memory request stream.

Abstract: The present invention relates to cylinder head gaskets on internal combustion engines, with at least three layers, namely a mid-layer, a function layer and a layer of a compression limiter. The mid-layer is arranged between the function layer and the compression limiter. The mid-layer has at least two essentially round fixing openings, outside a sealing region. The compression limiter is beaded around the edges of the fixing openings in the region thereof, and in this way fixes the compression limiter to the mid-layer. The function layer has recesses in the region of the fixing openings of the mid-layer, in order to accommodate the beaded region of the compression limiter, without increasing the total thickness of the gasket in the region of the fixing of the compression limiter.
