Backend electronics (BEE) commonly employ a high speed link to provide both fast and slow control to frontend electronics (FEE). In addition, the backend is responsible for trigger preprocessing and data readout. Typically, this high-speed link is shared by many frontend channels. Under such conditions, the processing time in the BEE for channels with lower readout priority varies significantly, especially in scenarios with high hit rate. This variability results in unpredictable or even unacceptable processing latency for demultiplexing and trigger preprocessing, even when zero-suppression and multiplexing are applied in FEE before data transmission. This paper addresses these issues through emulation study and proposes the Check-Sort-Push (CSP) mechanism as a solution. The necessity and advantages of this proposal are demonstrated using simulation and emulation under high hit rate conditions. An implementation in firmware is presented. Finally, the application of the CSP mechanism in the improved Resistive Plate Chamber (iRPC) system for CMS Phase-2 upgrade will be discussed, along with analysis results based on test beam data.
