You can do this using gettimeofday().The gettimeofday returns the time in
seconds and microseconds.
gettimeofday(T1, NULL);
// Process 100 frames
gettimeofday(T2, NULL);
The delta between T1 and T2 should give the time for processing 100 frames.

If you are using DVSDK, the Davinci Multimedia Application Interface (DMAI)
provides an abstraction for thread synchronization called Rendezvous. It is
typically used for initialization but can also be used for synchronization
during regular processing.
Even if you don't use this module, you
What are the attributes configured for TraceUtil in the XDC cfg file? By
default, the CE traces will be redirected to /tmp/cearmlog.txt. It looks like
you have set the environment variables CE_TRACEFILE so it gets redirected to
trace/cearmlog.txt. If the directory trace doesn't exist, there
Zhenfeng,
As Sid pointed out, the bus error is due to access of int32 data at non word
aligned address.
You have turned on structure packing with the #pragma directive. If this was
not done, the compiler would have padded 3 bytes between the char 'm' and int
'data'. In that case, the int

What's the error coming now? Does it stop after the NFS boot procedure?
If you have moved to a new kernel, you might want to use the target file system
associated with this kernel.

There could be several reasons:
1. Does the EVM network configuration contain the correct gateway IP?
2. Is the correct DNS server configured? If not, this needs to be added as
part of DHCP options or in the static IP configuration.
3. If you have the EVM inside the corporate network, the

Before accessing the TSC registers, you need to enable them by calling:
TSC_enable();
To get the DSP cycles, the best option is to use TSC_read(). This returns a 64
bit unsigned int containing the value of both TSCH and TSCL registers.

When you create the socket, try using IPPROTO_TCP instead of 0 as the protocol
for both the client and server. I believe this should solve your problem.

It depends on the driver interface you are using - V4L2 or FBDev. The V4L2
specification has ioctl commands for Dequeuing and Queuing a user buffer with
the display driver. On the other hand, the FBDev interface doesn't support user
pointers - driver buffer allocation is only through memory
The following error indicates that ti.sdo.utils.trace package doesn't
get included as part of the build. This package is present in
$(CE_INSTALL_DIR)/cetools/packages. If you include the cetools package
as part of your XDC_PATH, the problem should be resolved.
It looks like a classic case of white space problem in bootargs. Ensure
that you type the bootargs and don't copy-paste from a word/pdf
document.
Specifically, the bootargs setting console=ttyS0,115200n8
