Matrix Core Programming on AMD CDNA3 and CDNA4 architecture

In this blog post, we walk through how to use Matrix Cores in HIP kernels, with a focus on low-precision data types such as FP16, FP8, and FP4, as well as the new family of Matrix Core instructions with exponent block scaling introduced in the AMD CDNA™4 architecture. Through code examples and illustrations, we provide the necessary knowledge to start programming Matrix Cores, covering modern low-precision floating-point types, the Matrix Core compiler intrinsics, and the data layouts required by the Matrix Core instructions.
