Results - Cygnal / 8051 / SDCC
[Cygnal]

Time measurements were obtained using an oscilloscope attached to a digital output. See the "Tests Performed" section for more details.
Un-bracketed times are those obtained when building for the large memory model.
Times in [brackets] are those obtained when building for the small memory model.

Test	Result
16bit addition	9.9μs [3.1μs]
16bit multiplication	24.0μs [13.68μs]
16bit division	364μs [108.4μs]
32bit multiplication	55.6μs
32bit subtraction	16.6μs
Bubble sort	412μs [201μs]
Block memory move and compare	5.48ms
Conditional branch to procedure	36.8μs [19.5μs]
Scheduler tick function
PUSH’ing and POP’ing	21.6μs [19.5μs]

Each test contains a small amount of code within a loop. This could result in the percentage of cache hits achieved during execution of the tests to be higher than that achievable during execution of a more representative application.

The memory requirements of some tests meant they could only be performed using the large memory model.
