in the development of database application, we often need to face complex SQL computation, such as the correlation computation in multi-layer grouping. Because SQL grouping must be aggregated at the same time and object-related access is not possible, dealing with such problems can be complex and can only be accomplished with advanced techniques for nesting multi-layered subqueries with window functions. The collector supports true grouping, intuitive object-related access, and easier resolution
generation of Cortex-M series. Some commands in the preceding table are SIMD commands. Work with hardware multiplier (MAC) so that all these commands can be executed within a single cycle. Benefiting from the support of SIMD commands, the Cortex-M4 processor is able to complete up to 32x32 + 64-> 64 operations in a single cycle, releasing the bandwidth of the processor for other tasks, instead of consuming computing resources by multiplication and addition. Consider the following complex arithm

The so-called hdvd (high-capacity DVD) has been on the market for a long time. At that time, netizens from some technical websites had a very lively discussion until the hdvd discs of a large number of TV series on the market hit the genuine market, the hdvd issue was followed by the media.
