Bridge
5.3.12 Code Performance Analysis
A keyboard report processing is used to analyze the code performance. A typical keyboard report
processing contains the following steps:
■ The bridge receives the keyboard report packet and process the packet. This step takes 108 µs.
■ MCU calls function handle_keyboard_report() to format USB packet and load this packet into the
endpoint buffer. This function consumes 118 µs.
As a result, it takes 226 µs for the bridge to process a keyboard report.
