AMD has released an update to its CodeXL unified tool suite to allow developers to speed up design in applications running on AMD processors. CodeXL is AMD's primary developer tool for generating detailed information about the real-world performance of AMD CPUs, APUs and GPUs.

AMD CodeXL version 1.6 provides GPU profiling capabilities and API-level debugging for OpenCL 2.0 applications. CodeXL 1.6 also introduces an advanced tool for profiling APU power consumption, which enables developers to reduce the power requirements of their application. These features significantly bolster the tools available to developers for creating applications on either Windows or Linux that take advantage of the inherent processing capability of heterogeneous system architecture (HSA), stated the company.

The CodeXL tool suite assists software developers and ISVs to use parallel programming by harnessing the compute power of AMD's high-performance CPUs, GPUs and APUs. CodeXL 1.6 includes advanced GPU debugging, GPU and CPU profiling and static OpenCL kernel analysis. With AMD CodeXL 1.6, developers can bring to life applications with tremendous performance, long battery life and smooth playback, the company indicated. AMD has also released a beta version of the AMD APP SDK 3.0 with comprehensive OpenCL 2.0 support. AMD APP SDK 3.0 contains a complete set of sample code illustrating how to use each of the major new features of OpenCL 2.0.

The power profiler samples a variety of counters that capture individual APU sub-components, including their power consumption, effective frequency and temperature. The profile data is displayed in real time using a rich and intuitive graphic representation, while the application session is in progress. A command line option is also available.
