  • Publication number: 20240036866
    Abstract: Disclosed herein are systems and methods for executing multiple instruction set architectures (ISAs) on a singular processing unit. In an implementation, a processor that includes a first decoder, a second decoder, instruction fetch circuitry, and instruction dispatch circuitry is configured to execute two separate instruction set architectures. In an implementation, the instruction fetch circuitry is configured to fetch instructions from an associated memory. In an implementation the instruction dispatch circuitry is coupled to the instruction fetch circuitry, the first decoder, and the second decoder and is configured to route instructions associated with a first ISA to the first decoder, and route instructions associated with a second ISA to the second decoder.

  • Patent number: 10941154
    Abstract: A process for preparing oxycodone hydrochloride, said process comprising hydrogenating 14-hydroxycodeinone in an alcoholic solvent and hydrochloric acid to form oxycodone hydrochloride, wherein (a) the hydrogenation is carried out in the presence of a heterogeneous platinum group metal (PGM) catalyst and hydrogen gas, (b) the hydrogenation is carried out at one or more temperatures greater than ambient temperature in the presence of a hydrogenation catalyst and hydrogen gas, wherein the solution of 14-hydroxycodeinone and hydrochloric acid is heated to temperature before it is exposed to the hydrogen gas, (c) the oxycodone hydrochloride comprises 6a-oxycodol in an amount <about 0.300 area % as determined by HPLC, characterized in that (d) the pH of the solution of 14-hydroxycodeinone and hydrochloric acid is in the range of about ?2.5 to about ?4.5; (e) the process is carried out in one pot, and (f) the oxycodone hydrochloride precipitates out of the solution.

  • Publication number: 20200118092
    Abstract: A BbyB architecture provides a novel architecture in which smart contracts can be made independently from the blockchain they are being built on. More specifically, the BbyB architecture acts as the middleman or exchange. It enables for diversified transactions to hedge the individual coins volatility, fraud, and specificity, while still maintaining the security of our immutable blockchains. In layman terms, it's a blockchain built on every other blockchain on the network.
