Abstract

fetched live from OpenAlex

The rising popularity of high-level synthesis (HLS) is due to the complexity and amount of background knowledge required to design hardware circuits. Despite significant recent advances in HLS research, HLS-generated circuits may be of lower quality than human-expert-designed circuits, from the performance, power, or area perspectives. In this work, we aim to raise circuit performance by introducing a transactional memory (TM) synchronization model to the open-source LegUp HLS tool [1]. LegUp HLS supports the synthesis of multi-threaded software into parallel hardware [4], including support for mutual-exclusion lock-based synchronization. With the introduction of transactional memory-based synchronization, location-specific (i.e. finer grained) memory locks are made possible, where instead of placing an access lock around an entire array, one can place a lock around individual array elements. Significant circuit performance improvements are observed through reduced stalls due to contention, and greater memory-access parallelism. On a set of 5 parallel benchmarks, wall-clock time is improved by 2.0x, on average, by the TM synchronization model vs. mutex-based locks.

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.
