Abstract
We describe a synthesizable implementation in VHDL of a parallel architecture for signal processing called DSP-RAM. DSP-RAM is an enhanced version of the earlier computational RAM (C-RAM) architecture proposed by Elliott (see Ph.D. thesis, Dept.of Electrical Engineering, University of Toronto, Canada, 1998). Like C-RAM, the new architecture integrates on the same chip both memory storage and single instruction stream, multiple data stream parallel data processing. Unlike in C-RAM, each processing element contains a multiplier-accumulator that can directly handle 16-bit data words; in contrast, C-RAM is organized to perform massively-parallel, bit-serial computation. The VHDL DSP-RAM model was verified by simulating three promising applications: FIR digital filtering, the discrete cosine transform (DCT), and vector quantization (VQ). A controller circuit along with a simple micro-programming language were also designed to facilitate the implementation of applications.

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 it
