BeagleBone Black GPIO Performance: PRU -> 2 memory mapped different GPIOs In this test we change two different GPIO-banks (0 and 2) from the PRU in order to estimate the maximum performance and check the coherence of the signals. Some interesting details: clock cycles per operation Most operations, such as ADD,SUB,QBxx,MOV,JMP etc.: 1 cycle LBBO [...]
