ROCmROCm is an Advanced Micro Devices (AMD) software stack for graphics processing unit (GPU) programming. ROCm spans several domains: general-purpose computing on graphics processing units (GPGPU), high performance computing (HPC), heterogeneous computing. It offers several programming models: HIP (GPU-kernel-based programming), OpenMP/Message Passing Interface (MPI) (directive-based programming), OpenCL. ROCm is free, libre and open-source software (except the GPU firmware blobs), it is distributed under various licenses.
Central processing unitA central processing unit (CPU)—also called a central processor or main processor—is the most important processor in a given computer. Its electronic circuitry executes instructions of a computer program, such as arithmetic, logic, controlling, and input/output (I/O) operations. This role contrasts with that of external components, such as main memory and I/O circuitry, and specialized coprocessors such as graphics processing units (GPUs). The form, design, and implementation of CPUs have changed over time, but their fundamental operation remains almost unchanged.
TegraNVIDIA Tegra est un processeur tout en un (SoC), dérivé de la famille d'architecture ARM produit par NVIDIA. Il est destiné aux appareils mobiles comme des smartphones, des PDA et des MID. Le processeur sera aussi présent dans les systèmes de navigation et de divertissement des automobiles, notamment chez Audi et le groupe Volkswagen. Il existe actuellement comme séries de processeurs le Tegra APX 2500, Tegra 600 et Tegra 650. Avec la série 600 ciblant le marché des PDA/MID et le APX 2500 ciblant les smartphones.
