Abstract
Implementing an algorithm on FPGA is intrinsically more difficult than programming a processor or a GPU. Processor-based implementations “only” require a program to control their pre-synthesized data path, while an FPGA requires that a designer creates a new data path and a new controller for each application. Several approaches have been proposed recently to ease FPGA design. The present work builds on Coarse-Grained Reconfigurable Architectures (CGRAs), and Overlay Architectures (OAs), that allow a designer to take advantage of a pre-compiled FPGA architecture and still provide a way to configure the system at a higher level. In the proposed architecture, a generic data-driven compute fabric is interfaced to standard processors. To validate the proposed architecture and design method, an illustrative example is developed in which a processor sends an RGB image to a processing fabric, where it is converted to Y, Cr, Cb. Results show that thanks to a DMA between the memory and the fabric, a speedup of 50 is reached compared to a pure software implementation running on a Microblaze processor.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
