加拿大安大略渥太华的Zarlink公司推出一种GP4020数字式基带信息处理器。这种处理器是一种供GPS接收机使用的完全数字式基带信息处理器,它集GP2021 12信道相关功能和先进的ARM7TDMI微处理器功能于一身。每条信道的相关器都装有相同的跟踪模块,微处理器内装萤火虫式MF1微控制器芯子,此外,还装有一个二次UART、一个BUILD串行输入输出,一个通用输入输出和监视功能。GP4020处理器的
Zarlink, of Ottawa, Ontario, Canada, is introducing a GP4020 digital baseband processor. This processor is a fully digital baseband processor for GPS receivers that combines the GP2021 12 channel-related functions with the advanced ARM7TDMI microprocessor capabilities. The correlator for each channel is loaded with the same tracking module. The microprocessor contains a FireFly MF1 microcontroller core. In addition, it also houses a secondary UART, a BUILD serial input and output, a universal I / O and monitoring Features. GP4020 processor
