Scalable and Unified Digit-Serial Processor Array Architecture for Multiplication and Inversion Over GF( $2^{m}$ )
Bibliographic record
Abstract
This paper proposes a scalable and unified digit-serial structure, with low space complexity to perform multiplication and inversion operations in GF(2m), based on the bit serial multiplication algorithm and the previously modified extended Euclidean inversion algorithm. In this structure, the multiplier and inverter shares the data-path and thus saves more area resources and power than the case of using separate data-path for each operation. Also, this structure is suitable for fixed size processor that only reuse the core and does not require to modulate the core size when the field size m is modified. This structure is extracted by applying a nonlinear methodology that gives the designer more flexibility to control the processing element workload. Implementation results for of the proposed scalable and unified digit-serial design and previously reported efficient designs show that the proposed scalable structure achieves a significant reduction in area ranging from 64.3% to 85.5% and also achieves a significant saving in energy ranging from 21.9% to 92.5% over them, but it has lower throughput compared with them. This makes the proposed design more suitable for constrained implementations of cryptographic primitives in ultra-low power devices, such as wireless sensor nodes and radio frequency identification devices.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
