Abstract: The present disclosure provides a preparation method of a surimi low-molecular-weight antifreeze peptide, and relates to the technical field of processing of aquatic products. The preparation method includes the following steps: step 1, with Larimichthys crocea as a raw material, decapitating and gutting the L. crocea, crushing the L. crocea into a surimi, decalcifying the surimi, extracting water-soluble crude protein with water, and freeze-drying to obtain the water-extracted crude protein powder of L. crocea; step 2, redissolving the water-extracted crude protein powder of L. crocea obtained in step 1 with water, and enzymatically hydrolyzing it with protease to obtain an enzymatic hydrolysate; and step 3, sonicating and dialyzing the enzymatic hydrolysate obtained in step 2 to obtain a dialysate with a molecular weight no more than 3,500 D, and freeze-drying the dialysate to obtain the surimi low-molecular-weight antifreeze peptide.

Abstract: A semantic processor for a hardware database management system is described that is operable to take statements in a standardized language and parse those statements. The semantic processor includes a tokenizer for separating the statement into its individual elements and identifying keywords and operators. A precedence engine then orders the elements of the statement into the proper execution order and a function compiler creates an execution tree and determines which element are free of dependencies and can be executed.

Abstract: A method for implementing a hardware database management system in hardware is described. A parser takes standardized database statements and converts those statements into a set of executable instructions and associated data objects. The executable instructions and data objects are then sent to the execution tree engine where an execution tree is created, the execution tree forming the order of execution for the executable instructions. The graph engine receives those executable instructions from the execution tree engine that require access to the database in memory and manipulates the information in the database as required by the executable instructions for implementing the standardized database statement.

Abstract: A database and database management system are implemented entirely in hardware. The information forming the database is stored in random access memory which is connected to a data flow engine. The data flow engine is able to process statements in standard database protocols such as SQL and XML, and to manipulate (read, write and alter) the database in accordance with the statements. The data flow engine is connected to a microprocessor that receives the statements from the database user or database application server and sends them to the data flow engine for processing. The results from the data flow engine are returned to the microprocessor and the microprocessor then returns the results to the user or application server.
