Ultimate CRC is a CRC generator/checker. Using generics the core can be fully customized. It creates a function of the data input and the CRC register using XOR-logic. Although the levels of logic gets very high for wide data inputs, the throughput still benefits from this architecture, as can be seen from the synthesis page.

本文将选用一块支持 BDS/GPS 双模定位并具有低功耗特 点的芯片 ATGM332D-5N-3X 作为手持定位终端的定位模块。 ATGM332D-5N-3X 支持两种卫星导航系统进行组合定位，包括中国的 BDS （北斗卫星导航系统）， 美国的 GPS 。该模块具有 32 个跟踪通道，两个卫星导航系统的 GNSS 信号可同 时被接收，从而实现联合定位的功能。 ATGM332D-5N-3X 模块具有高灵敏度、 低功耗、低成本等特点，适用于船舶导航、车载导航、可穿戴设备等。(This article will choose a piece of support BDS/GPS Dual mode positioning with low power consumption Point chip ATGM332D-5N-3X As a positioning module for a handheld positioning terminal.
