The DSP/BIOS Utilities Product provides a set of tools that is
complimentary to the DSP/BIOS real time operating system. The DSP/BIOS
Utilities consists of the following packages:
- ti.bios.utils: The utils package contains the following module:
- Load:
- Used for computing and returning the CPU load of the DSP.
- ti.bios.log.support: The log support package contains the following
modules:
- LogTrack:
- Supports tracking of CPU load, user values residing in Target
memory, and dynamic task creation via DSP/BIOS message logs.
- LogAux:
- Provides an API set that is supplementary to DSP/BIOS log,
which gives the user more control over DSP/BIOS logs. This includes
APIs for:
- Enabling or disabling a set of DSP/BIOS logs.
- Flushing and discarding data from a set of DSP/BIOS
logs.
- Reading raw DSP/BIOS log data from Target memory.
- ti.bios.log.ndk: The log ndk package contains the following module:
- LogServerCgi:
- Provides a CGI (Common Gateway Interface) command set used to
access the DSP/BIOS logs via an internet connection. The following
CGI functionality is supported for accessing DSP/BIOS logs via
internet connection:
- Enabling or disabling a set of DSP/BIOS logs.
- Flushing and discarding data from a set of DSP/BIOS
logs.
- Reading and writing a word of data to Target memory.
- Getting the DSP clock speed.
- Setting up to four addresses of user values, which will be
printed out to a DSP/BIOS log.
- Capturing the entire contents for a set of logs in the
program.
- Streaming the contents of a set of logs indefinitely.
- ti.bios.rtadecode
- The rtadecode package provides a program which decodes DSP/BIOS
RTA data from the DSP.
- The rtadecode program can be used to process the binary log data
that is read using the ti.bios.log.support and ti.bios.log.ndk packages.
- The rtadecode program will print out information about the BIOS
LOG_printf() statements in the program, such as the format string.
