Abstract
Current FPGA soft processor systems use dedicated hardware modules or accelerators to speed up data-parallel applications. This work explores an alternative approach of using a soft vector processor as a general-purpose accelerator. The approach has the benefits of a purely software-oriented development model, a fixed ISA allowing parallel software and hardware development, a single accelerator that can accelerate multiple applications, and scalable performance from the same source code. With no hardware design experience needed, a software programmer can make area-versus-performance trade-offs by scaling the number of functional units and register file bandwidth with a single parameter. A soft vector processor can be further customized by a number of secondary parameters to add or remove features for a specific application to optimize resource utilization. This article introduces VIPERS, a soft vector processor architecture that maps efficiently into an FPGA and provides a scalable amount of performance for a reasonable amount of area. Compared to a Nios II/s processor, instances of VIPERS with 32 processing lanes achieve up to 44× speedup using up to 26× the area.

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
