Abstract

fetched live from OpenAlex

The programmable clock networks in FPGAs have a significant impact on overall power, area, and delay. Not only does the clock network itself dissipate a significant amount of power, since it connects to every latch on the FPGA and toggles every cycle, but the design of the clock network also affects how efficiently the rest of the application can be implemented since it imposes constraints on the CAD tools which map the application onto the FPGA. To examine this tradeoff, this paper describes and compares new clock-aware placement techniques and then examines how the clock network architecture affects overall power, area, and delay. Our results show that the placement techniques used to make placement clock-aware have a significant influence on power and delay. On average, circuits placed using the most effective techniques dissipate 9.9% less energy and were 2.4% faster than circuits placed using the least effective techniques. Moreover, the results show that the clock network architecture is also important. On average, FPGAs with an efficient clock network were up to 12.5% more energy efficient and 7.2% faster than other FPGAs.

Teacher imitation

Not 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.
