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	e5d13917b2	feat(cam): add Bernoulli noise mask module and cocotb tests ... - Add noise_mask_bernoulli.sv RTL module for probabilistic masking - Add cocotb test suite with reset, threshold, determinism, and distribution checks - Update rtl-sources.mk to include new module - Fix PYTHONPATH in devenv.nix shell hook	2026-05-26 19:41:17 +08:00
SikongJueluo	e4cbb5e30d	feat(hw/rtl): implement full Top-K CAM search pipeline with serial result output ... - add TOPK_K, FIFO_DEPTH, RESULT_SERIAL parameters to cam_params - add candidate_fifo: synchronous ready/valid FIFO for (row, score) candidates - add topk_tracker: tracks top-K candidates with clear/ready handshake - add result_serializer: serializes packed Top-K array into rank-ordered stream - refactor match_engine_pipeline from 4-state to 8-state Top-K pipeline - extend cam_top with serial Top-K interface (result_rank/row/score/last) - add backward-compatible top1_index/top1_score aliases from rank-0 beat - add comprehensive tests for all new modules	2026-05-19 22:43:21 +08:00
SikongJueluo	ca167e79c6	refactor(hw/sim): extract common cocotb make infrastructure into shared mk/ directory ... - Split monolithic hw/sim/Makefile into modular include files (mk/cocotb-common.mk, mk/rtl-sources.mk) - Add per-module test Makefiles (cam_core_banked, cam_read_noise, cam_write_noise, match_engine_pipeline, perf, top) - Add missing simulation tools (yosys, graphviz, xdot) to devenv.nix - Fix path handling in sweep_noise.py and test modules to be HASH_BITS-aware	2026-05-16 19:24:17 +08:00
