Architecture and implementation of chip multiprocessors: custom logic components and software for rapid prototyping
Bibliographic record
Abstract
This work describes components and software tools in support of rapid prototyping in programmable logic for research on chip multiprocessors. Contemporary programmable logic chips offer considerable on-chip logic and memory resources. Prototyping of systems in programmable logic chips is faster and less costly than full-custom chip design. The first contribution that is described in this paper is a collection of original research-oriented logic components that provides processor, memory, and interconnect functionality for rapid prototyping. Because these are original components, and not proprietary vendor-supplied components, they may be arbitrarily extended and modified to suit research needs. The second contribution is a set of enhanced software tools for generating executable code. The third contribution is user-configurable software for testing and evaluating prototype chip multiprocessor implementations in hardware. In addition to describing these contributions, this paper provides results from implementing and testing prototype components and complete chip multiprocessors, including simulation waveforms, logic chip resource utilization, and observations of hardware operation.

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.
