Parallel Studio
(ePS)
The Tool for Parallel Programming
emmtrix Parallel Studio (ePS) helps you to optimize the performance of your embedded applications on multicore, GPU and DSP architectures as well as any combination of these processing units. Our tool automates and radically simplifies the parallelization process to the point where you simply need to take a few decisions to get good results. The patented graphical user interface (GUI), together with a number of reports, provides full transparency and leaves you in complete control at every step of the process.
Use your existing C code as starting point for the parallelization in ePS. Together with ePS Qualification Kit the parallelization can be performed for applications with functional safety requirements like ISO 26262 or DO-178C.
ePS Workflow
Figure 1: Automated Workflow for Parallel C Code Generation and Optimization
The core of emmtrix Parallel Studio is a C source-to-source compiler that takes sequential C code as input and generates optimized source code for a selected target architecture. The sequential C code can be either handwritten legacy code, generated by our code generators emmtrix Code Generator (for MATLAB®, Scilab or GNU Octave scripts), emmtrix Model Code Generator (for Simulink) and emmtrix C++ to C Compiler (for C++) as well as generated from 3rd party tools like MATLAB® coder or Simulink coder.
For optimizing your code, ePS analyzes the source code, estimates its performance and exploits different kinds of parallelism (thread-level, data-level and loop-level). For example, in case of multicore processors independent code parts are identified and distributed to different cores or vectorization is applied for vector processors. The parallelized or vectorized output source code can be directly compiled and tested for the target architecture using development boards or simulators. For functional safety, a qualification kit can compare the sequential input and parallel output code to prove the absence of errors.
