These extensions allow for cross-compilation and deployment and execution of - your output into a QEMU emulation session. - You can also perform cross-debugging and profiling. - The environment also has a suite of tools that allows you to perform - remote profiling, tracing, collection of power data, collection of - latency data, and collection of performance data. - </para> - <para> - This section describes how to install and configure the Eclipse IDE -
