Running The SoC Analyzer

Built upon Texas Instruments' eXpressDSP data visualization technology
(DVT), the SoC Analyzer simplifies debugging, analysis, and optimization
of DVEVM applications. It collects execution, interaction, and resource
utilization logs from Linux, DSP/BIOS, Codec Engine, and drivers and
presents system-level analysis and graphical visualization such as:

❏

System execution flow

❏

System performance

❏

Resource utilization

❏

Processor interaction

Install the SoC Analyzer as described in Section 4.3.4.
