Abstract

fetched live from OpenAlex

A key aspect of Coarse-Grained Reconfigurable Arrays (CGRAs) is dynamic reconfigurability, where multiple configurations, or contexts, are loaded into the CGRA to time-multiplex its resources. This feature allows the CGRA to accommodate larger applications without a significant increase in its size. Context switching is typically centralized, using the system clock to synchronously cycle through configurations simultaneously across CGRA resources. This approach is unable to efficiently accommodate variable-latency operations. Elastic CGRAs were proposed to handle such operations via an architecture that operates according to a dataflow paradigm. However, elastic solutions are single context by nature, which limits their applicability to smaller application kernels. Time-multiplexed multi-context and elastic CGRAs are thus naturally incompatible with one another. In this paper, we aim to overcome this incompatibility and propose an architectural framework that is capable of generating elastic CGRAs with multi-context support. Elastic primitives that traverse contexts in a distributed fashion are introduced. We also extend conventional mapping solutions to handle the new architectures. Finally, we evaluate the area and performance overhead for elastic multi-context CGRAs over single context ones with equal processing capacity.

Full frame distilled prediction

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.
