Distributed Systems
Published in Vivek Kale, Digital Transformation of Enterprise Architecture, 2019
A classic example of this architecture is the microprocessor pipeline, whereby multiple instructions are executed at the same time by completing a different phase of each of them. We can identify the phases of the instructions as the filters, whereas the data streams are represented by the registries that are shared within the processors. Another example are the Unix shell pipes (i.e., cat <file-name>| grep<pattern>| wc -l), where the filters are the single shell programs composed together and the connections are their input and output streams that are chained together. Applications of this architecture can also be found in the compiler design (e.g., the lex/yacc model is based on a pipe of the following phases | scanning | parsing | semantic analysis | code generation), image and signal processing, and voice and video streaming.

Pipelined Multibit Tries
Published in Weidong Wu, Packet Forwarding Technologies, 2007
The MinMax algorithm is intended for use in hardware design—an important measure of performance in such cases is the worst-case memory usage (in addition, to lookup and update times). In other words, given a k-stage pipeline and a prefix table of size N with a maximum prefix length of W, we would like to compute the worst-case memory size for a pipeline stage. Let the worst possible input of N prefixes to the MinMax algorithm be WC, and let maxWC be the size of the maximum pipeline stage as computed by the MinMax algorithm.

Different samples starting from the following composition, 90 wt-% carbide phase and 10 wt-% metallic binder, have been prepared for milling. The starting mixture contains Co as a metallic binder, due to its good wettability of the carbide phase upon sintering [14,15], and WC as carbide phase. The WC phase contains small amounts (<0.5%) of Cr3C2 and VC dopants. Different milling experiments were pursued, with durations ranging from 4 h up to 10 h, using a Netzsch PE5 attrition mill. All the samples have been processed using 100% filling factor and an organic milling medium. Two organic solvents have been used: acetone (polar) and isohexane (nonpolar). Considering the abrasive character of the powder, the used milling balls (7 mm diameter) are manufactured from similar material to the processed material (WC–Co) to prevent powder contamination. The solvent removal has been performed in a Büchi Rotavapor at the pressure of 40 mbar at room temperature.
