Introduction to TTL, an Open Source Tensor and Tiling Library for OpenCL
Christopher Gearing, Ayal Zaks · International Workshop on OpenCL · 2023
OpenCL has an Image data type to represent multi-dimensional arrays of image data for processing in device Kernels. Whilst providing powerful functionality for image processing, they are designed towards the capabilities of GPUs and provide closed opaque functionality and data formats. This presentation presents a recently released Open-Source library, “Tensor and Tiling library”. TTL has been created to support multi-dimensional data for non-GPUs. Like the GPU Image type, the TTL tensor type has built-in attributes to describe its shape, layout and underlying data. The library provides methods for reading, writing, reasoning about the relative positioning of related Tensors, and attributes of the data beyond the extent of the Tensor.
