SikongJueluo	8b4d4c1b57	refactor(cam): remove read noise from noise architecture (Phase 2) ... - Make cam_read_noise a pass-through module, removing all noise injection logic - Switch write noise to use noise_mask_bernoulli instead of noise_mask_grouped - Add state machine to cam_write_noise for mask generation timing - Remove noise_mask_grouped.sv (no longer needed) - Remove read noise parameters from cam_noisy and cam_top - Update simulation and benchmark code to reflect read noise removal - Sync documentation to reflect Phase 2 architecture	2026-05-26 23:45:52 +08:00
SikongJueluo	1ff9a5f18b	feat(retrieval-benchmark): add support for external pre-prepared CAM retrieval datasets with recall@k metric ... - Add just recipes for preparing CIFAR10/100 hash artifacts and running benchmarks - Add CAM_RETRIEVAL_DATASET env var support in Makefile - Add load_retrieval_dataset_npz() to load pre-prepared retrieval datasets - Add label_hits counter and recall@k metric for retrieval evaluation - Rename macro_recall to retrieval_recall to clarify semantics	2026-05-22 21:07:10 +08:00
SikongJueluo	e1bed00cc4	feat(retrieval): add CAM retrieval benchmark with topk scoring and read noise support ... - Add cocotb benchmark infrastructure under hw/sim/benchmarks/retrieval/ with Makefile - Implement test_retrieval_benchmark.py supporting configurable topk-k, read/write noise - Add cluster-based synthetic dataset generator with configurable bit-flip rates - Add reference model functions: match_topk, match_topk_from_scores, score_rows_with_read_noise - Add .justfile shortcuts: cam-test-retrieval-no-noise, cam-test-retrieval-read-noise - Add TOPK_K to Verilator EXTRA_ARGS via cocotb-common.mk - Add unit tests for topk sorting logic and stateful read-noise scoring	2026-05-22 19:04:54 +08:00
