Example Embodiment
[0023] like figure 2 As shown, the UHF RFID baseband processing SOC chip of the present invention includes a CPU module, an on-chip bus, a memory interface, a DAC output channel, an ADC input channel, a UHF RFID hardware multi-protocol processing unit, a man-machine interface, a high-speed communication interface, a low-speed communication interface, timer module, low power consumption control module and other modules,
[0024] CPU module: The SOC chip has a built-in 32-bit CPU core (based on OR1200). The CPU core can use instructions to complete functions such as coordination, configuration, and working status detection of each component module in the entire chip. Various embedded operating systems (such as Windows CE or Linux, etc.) can be embedded in order to achieve more flexible functions and provide users with a good program interface. In addition, the baseband signal can also be digitally filtered, encrypted, decoded, coded, decoded, etc. processed by executing softwa...
