Description
The contribution will describe a new floating-point unit, and new integer instructions that have been implemented in LEON2-FT. The new integer instructions implement SIMD-within-a-register operations that are beneficial for speeding-up GNSS/SDR as well as cryptographic or image processing workloads. The FPU can be configured to act as a drop-in replacement of the former Meiko FPU that is no longer available, or to support just selected operations in user-defined precision (e.g. FP16 or bfloat16), with other operations and/or precisions computed in software. The main goal of these extensions is to increase the potential of LEON2-FT for current and future on-board data processing.
