CPU is near 100% because it's busy to send drawing command to the GPU. It is usign a FIFO to send those commands and the most of the time it's waiting for the FIFO to be free. This is not a big deal for the normal use of the library.
Anyway, you say that the number are not great, but compared to what? This is a GPU designed for automotive application, so it should be a trade-off between performance and power consumption. Consider that this chip uses around 1W of power, so you can't compare it's performance with a new 100W ATI board. 2010/5/5 Andre DRASZIK <andre.dras...@st.com>: > Hi, > > On Tue, 2010-05-04 at 17:43 +0200, Matteo Canella wrote: >> Is there anyone here using fujitsu GPUs with DirectFB who can give me >> a benchmark to compare? > > I know nothing about that GPU, but... > >> I'd like to understand if we can be happy with our stream throughput scores. > > ...your CPU load is 100% on all these tests.
