Heterogeneous Distributed SRAM Configuration for Energy-Efficient Deep CNN Accelerators
Bibliographic record
Abstract
Convolutional Neural Networks (CNNs) are often the first choice for visual recognition systems due to their high, even superhuman, recognition accuracy. The memory configuration of CNN accelerators highly impacts their area and energy efficiency, and employing on-chip memories such as SRAMs is unavoidable. SRAMs can reduce the number of energy-hungry DRAM accesses by storing a large amount of data locally. In this paper, we propose a new on-chip memory configuration, for a certain class of CNN accelerators that divides the memories into two groups. The first group consists of shallow but wide SRAMs into which parallel computational units accumulate intermediate results. The second group includes narrow but deep SRAMs shared between adjacent computational units to store then transfer final results to the external DRAM without interrupting the computation process. Implementation results show that the proposed configuration reduces the area by 21 % and improves the energy efficiency by 18% compared to designs which use an ordinary ping-pong structure for SRAM-DRAM data transfer.

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.
