Time measurements were obtained using an oscilloscope attached to a digital output. See the "Tests Performed" section for more details.
Results are with the development tools using optimization for speed unless otherwise stated.
Test Result 16bit addition 30.2μs 16bit multiplication 30.2μs 16bit division 38.4μs with optimization, 70.4μs with no optimization. 32bit multiplication 143.6μs 32bit subtraction 52μs with optimization, 77.6μs with no optimization. Bubble sort 1.07ms with optimization, 2.8ms with no optimization. Block memory move and compare 1.65ms with optimization, 1.72ms with no optimization. Conditional branch to procedure 132.8μs with optimization, 432μs with no optimization. Scheduler tick function 45.6μs with optimization, 62μs with no optimization. PUSH’ing and POP’ing 248μs
The same inline assembler was used to perform this test with both the Open Watcom and Borland compilers. The very slight discrepancy in the results obtained with the different development tools can be attributed to the setting and clearing of the digital output - which used a C function.
