The present invention relates to a BISS C protocol data acquisition and display apparatus. The apparatus comprises an encoder data reception and display panel, a power source and a display screen; the power source is capable of supplying power for the encoder data reception and display panel; the display screen is used for displaying data output by the encoder data reception and display panel; and the encoder data reception and display panel comprises a DSP (Digital Signal Processor) plus a DPGA (Field Programmable Gate Array), an external FLASH, an interface chip, a communication chip and the like. The apparatus provided by the present invention adopts a "DSP+FPGA" hardware combination mode and performs data exchange with an absolute-type encoder of BISS C mode data; the FPGA implements whole logic and time sequence control and configures each interrupt of the DSP, and the DSP implements exchange and processing of data, so that logic units have jobs divided clearly, the control program is simplified, and the speed and accuracy of data exchange are improved.
