Abstract: A method of automatically translating an opcode summary table into an Architecture Description Language (“ADL”) can be employed to efficiently design and test a microprocessor instruction set. An opcode summary table is analyzed and code is generated in an ADL. The generated code can be optimized by first analyzing the opcode summary table to find groupings and sub-groupings of instructions based on similarities. The optimized code can be generated by first generating code for common elements within the sub-group, then generating code for each instruction within the sub-group. This process would repeated for each group in the opcode summary table. The result is an ADL description of the opcode summary table.

Abstract: The dew points of condensible hydrocarbon and water in a gas stream are determined independently in a single run by observing changes in intensity of light scattered from a mirror surface which is cooled to below both of the dew points. A decrease in intensity denotes the hydrocarbon dew point while an increase in intensity denotes the water dew point. The apparatus is simple and operates automatically. The mirror surface has a first polished and highly reflective portion and a second, roughened, less reflective portion. The intensity of scattered light is preferably monitored separately for each mirror portion.
