Compression and decompression CPU usage in Leon 3

[Rafael Morales]

Dear all,

I'm using a Leon 3 with RTEMS 4.10.

When I run a compression/decompression algorithm (zlib or promDecode 
from mkprom sources) on KB of data,
my other RTEMS tasks seems to be frozen.
I've tried to put the compression/decompression in a separate task with 
low priority, but no luck.

In theory, a more privileged task should stop the compression and start 
to run, but I see just the opposite.

Any idea?

Thanks in advance.
