WebThe RX-Stick demonstration program runs 1,000,000 iterations of the Dhrystone; this takes between 3 and 4 seconds to complete. While the test is running, the RX is using a high-resolution timer to record the execution time. At the conclusion of the benchmark, the number of Dhrystones per second and number of Dhrystone MIPS per MHz are computed. The Dhrystone benchmark contains no floating point operations, thus the name is a pun on the then-popular Whetstone benchmark for floating point operations. The output from the benchmark is the number of Dhrystones per second (the number of iterations of the main code loop per second).
