ywkang 81ce55571d Rename impl names: add builtin. prefix for clear provenance 
- components.yaml: all builtin impls use builtin.xxx naming
- topology.yaml: all impl references updated to builtin.xxx
- builder.py: hardcoded ucie impl → builtin.ucie
- Tests: all impl string references updated

Convention: builtin.<name> for built-in, custom.<name> for user-defined.
382 tests passing.

ywkang 1d95df4bee Restructure legacy backups, remove pe_accel, fix DMA self-routing 
- Move builtin_legacy/ → legacy/builtin/ (cleaner structure)
- Move pe_accel_legacy/ → legacy/pe_accel/
- Remove custom/pe_accel/ (replaced by new builtin)
- Remove pe_scheduler_v2 from components.yaml
- Switch topology.yaml to pe_scheduler_v1 (new builtin)
- Fix PE_DMA self-routing: handle consecutive DMA_READ stages
  (same component consecutive stages processed in-place, not via port)

382 tests passing.

ywkang b6eb97c49a Implement ADR-0021: PE pipeline refactor with token self-routing 
Step 1-2: Backup existing code
- builtin/ → builtin_legacy/ (unchanged backup)
- custom/pe_accel/ → custom/pe_accel_legacy/ (unchanged backup)

Step 3-4: New pipeline types and tiling
- pe_types.py: StageType, Stage, TilePlan, PipelinePlan, PipelineContext, TileToken
- tiling.py: generate_gemm_plan, generate_math_plan (ported from pe_accel)

Step 5: Component implementations (ADR-0021 D4-D6)
- PE_SCHEDULER: _feed_loop (singleton FIFO feeder) + plan generation
- PE_FETCH_STORE: new component — TCM ↔ Register File
- PE_GEMM: TileToken pipeline + legacy PeInternalTxn dual-mode
- PE_MATH: TileToken pipeline + legacy dual-mode
- PE_DMA: TileToken pipeline + legacy + fabric Transaction triple-mode
- PE_TCM: TcmRequest handler with dual-channel BW serialization

Step 6: Infrastructure
- topology.yaml: pe_fetch_store component + chaining edges
- components.yaml: pe_fetch_store_v1 registration
- builder.py: PE_COMP_OFFSETS, _add_pe_internal_edges, PE view positions
- Tests: node/edge counts, PE component sets updated

All components handle both TileToken (pipeline) and PeInternalTxn (legacy).
Token self-routing: components read next stage from token.plan, chain via out_port.
366 tests passing.

ywkang eb792e6212 Remove xbar/noc remnants, rule-based cube-view connectors 
- Delete xbar.py and noc.py (TwoDMeshNocComponent) — unused since router mesh
- Remove xbar_v1/noc_2d_mesh_v1 from components.yaml
- Fix pe_to_xbar → pe_to_router in routing exclusion set
- Fix xbar_to_hbm_bw_gbs → hbm_to_router_bw_gbs in report.py
- Update all docstrings/comments referencing xbar/bridge → router mesh
- Cube-view connectors: rule-based _connector_points helper
  - PE↔router: single diagonal line (not chevron)
  - UCIe N/S: 45°→horizontal→45°
  - UCIe E/W: 45°→vertical→45°
  - HBM ports: 45°→horizontal→45°

ywkang 114510d4b9 Add SchedulerV2 (pe_accel), DPPolicy overrides, and new benchmarks 
- Add cycle-accurate PE accelerator scheduler (SchedulerV2) with tiled
  GEMM/Math pipelines (DMA_IN → GEMM → MATH → DMA_WB)
- Add DPPolicy num_pes/num_cubes/num_sips overrides for single-PE testing
- Support tuple target_pe for targeting specific PE subsets
- Add gemm_single_pe and gpt3_qkv benchmarks
- Switch default topology to pe_scheduler_v2

ywkang 63669f82cb Add SIP-level tensor parallelism, component registry YAML, VA offset verification 
- DPPolicy: 3-level (sip/cube/pe), unified naming (column_wise/row_wise)
- PE_CPU: auto num_programs from cube shard count
- context.launch(): per-SIP KernelLaunchMsg with local va_base + auto local shape
- deploy_tensor: removed mmus param, MMU mapping is context-only responsibility
- ComponentRegistry: YAML-based lazy loading (components.yaml), impls→builtin rename
- VA offset bench + tests: 2D/1D, standard Triton kernel pattern
