Performance Test Analysis of MODBUS CRC Calculation Algorithms on Raspberry Pi 3B Model

[RohiitDev]

I conducted the performance test of the MODBUS_CRC16 Calculation Algorithms on Raspberry Pi 3B Model so that there's result of Algorithm 4 as well. Please update readme or I can do a pull request.

The results of our testing is here:

CPU Model:
ARMv7 Processor rev 4 (v7l)
ARMv7 Processor rev 4 (v7l)
ARMv7 Processor rev 4 (v7l)
ARMv7 Processor rev 4 (v7l)

Algorithm 1 Execution Time

$ time ./MODBUS_CRC16 1 1000000
real    2m14.184s
user    2m13.645s
sys     0m0.084s

Algorithm 2 Execution Time

$ time ./MODBUS_CRC16 2 1000000
real    1m30.817s
user    1m30.562s
sys     0m0.005s

Algorithm 3 Execution Time

$ time ./MODBUS_CRC16 3 1000000
real    0m17.883s
user    0m17.827s
