GP2021 GPS 12 channel Correlator Advance Information DS4077 - 2.6 July 1996 The GP2021 is a 12 channel C/A code baseband correlator for use in NAVSTAR GPS and GLONASS satellite navigation receivers. The GP2021 complements the GP2015 and GP2010 C/A code RF downconverters available from Mitel Semiconductor. The GP2021 is compatible with most 16 bit and 32 bit microprocessors, especially those from Motorola and Intel, with additional on–chip support for the ARM60 32 bit RISC processor. When the ARM60 is used, the on–chip memory management functions allow implementation of a full GPS receiver with minimal external logic. The GP2021 allows individual channel de–activation, for systems not requiring full 12 channel operation, to save power and processor loading.
