1Title: Shared DSP Support
2
3Description:
4
5This test is only for ARC targets and uses two tasks to:
6
7  1) Test load and store dsp registers (including arch specific registers)
8  2) compute complex vector product and check for any errors
9
10This tests the ability of tasks to safely share dsp hardware
11resources, even when switching occurs preemptively (note that both sets of
12tests run concurrently even though they report their progress at different
13times).
14
15The demonstration utilizes semaphores, round robin scheduling, DSP and XY
16memory support.
