High speed asynchronous structures for inter-clock domain communication
Bibliographic record
Abstract
This paper describes a globally asynchronous, locally dynamic system (GALDS) design paradigm. In a GALDS design, many synchronous blocks are inter-connected using dedicated asynchronous links. Each synchronous block is associated with a local clock generator and features dynamic frequency scaling in order to utilize the least possible power for the required performance to be achieved. Two different asynchronous structures are explored in this paper and they each feature high throughput, modular design and high tolerance to metastability errors that occur when communicating between clock domains. These structures utilize a 4-phase dual track asynchronous control circuit to control either a single direction FIFO with data traveling uniquely in one direction or a bidirectional FIFO that is capable of transmitting data simultaneously in both directions by precisely controlling when data has access to a common, shared datapath. These structures have been created in TSMC's CMOSP18 technology.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
