Connect DVP to Tiny DMA2/request 11, IRQ15 and the camera pad/reset lifecycle. Harden shared capture CDC, frame statistics, per-row size validation and HAL cleanup while preserving the Mini DMA3 binding and existing register ABI. Add deterministic capture/recovery firmware, source-bound evidence tooling, focused RTL/host tests and compact netlist acceptance. Preserve SAFE24, 128 KiB main SRAM, private Crypto storage and the locked dependencies. Retained validation: focused RTL, host/policy checks, Mini firmware, and ICS55/IHP130 RECOVERY, QVGA, synthesis and boot/DVP netlist checks pass. Full-system VGA remains historical; long full Icarus and broad regressions remain deferred. Global publication/format gaps and negative observational STA are retained, not reported as passing qualification. Specification: docs/ip/tiny-soc.md, TINY-R2-P9. Evidence: docs/ip/tiny-soc-verification.md.

Reproducible Build Profiles
This directory contains committed Make configuration profiles. Each profile
selects SoC, PDK, ISA, CSR support, application, linker layout, and the
supported validation tier. MINI_MODE=PRODUCT fixes Hazard3 and VexiiRiscv as
LP/HP harts and exposes one fixed EXT-L plus one fixed EXT-H slot. The separate
cluster/mini-mpw.mk profile retains C0-C3 and the selectable user-IP mux.
ci/ contains pull-request profiles, cluster/ contains configurations
requiring site tools or PDKs, and benchmark/ contains fixed-workload baseline
profiles. The ihp130-hazard3-coremark.mk profile is the automated SRAM
CoreMark quick measurement; its -standard counterpart is reserved for a
10-second hardware run. The nightly workflow reuses the IHP130 CI profile and
runs the quick CoreMark profile.
ci/ihp130.mk is the Mini PRODUCT IHP130 profile used by the NPU-P6 flow. At
root revision d084002bfe99, P0 numerical qualification and KWS/VWW corpus
generation passed, and the RV64 KWS/VWW bundles passed payload/header
validation. Stage-instrumented KWS shard 0 and shard 1 both stop in the pinned
portable-C reference at reference-start; no NPU_P6_CASE or P6
qualification report is claimed. See the NPU verification contract
and retained logs under
build/ihp130-2026-10-01-10-30-b2e490436ac7/npu/p6/.
ci/ihp130-hp.mk is the asymmetric Linux application profile. It starts HP
from the external 72 MHz safe clock and LP from REF24, runs hp_boot entirely
from 32 KiB on-chip SRAM, enables VexiiRiscv Zicbom with 64-byte blocks, and
generates VexiiRiscv RTL only below the selected build variant. It is not part
of the supported PR matrix until Linux boot, HP performance, synthesis, and
timing evidence are qualified.
ci/ihp130-rtthread.mk selects the same RV64 HP hardware and LP loader for
the pinned RT-Thread M-mode selftest. Run make setup-hp-rtthread, then
make CONFIG=configs/ci/ihp130-rtthread.mk SIMU=VERILATOR hp-rtthread-sim.
ci/ihp130-apu.mk is the RV64 APU LP/HP evidence profile. It runs
apu_release from PSRAM, stages the embedded APUMC/APUM/WAV/KWS assets through
SDRAM, performs the LP-only image loads, hands APU ownership to HP, and checks
HP-submitted WAV/KWS jobs plus the LP-only register fault probe in the full-SoC
Verilator simulation via hp-apu-sim.
All PRODUCT profiles use rv64imafdc_zicbom_max; LP compiler/ISA remain RV32.
ci/ihp130-xpi-flash-loader.mk builds the SRAM-only XPI NOR service image used
by GDB/OpenOCD; it is a programming utility, not a normal boot application.
Start builds from a committed profile rather than setting an unreviewed mix of
variables on the command line.
SRAM_SIZE_KIB selects 4, 16, 32, 64, or 128 KiB of on-chip SRAM and is part
of the build variant key. IHP130, GF180, and SKY130 CI profiles select eight
4 KiB banks for 32 KiB total and enable both the interface and technology
macro. The committed ICS55 Mini profile now uses the locked OpenECOS SRAM
release; its PLL remains absent. Capacity is selected by each committed
profile: the executable IHP130 Tiny profile uses 128 KiB. Do not infer a
Tiny capacity or PLL setting from a Mini profile.
local/ics55.example.mk remains available for an optional PLL experiment.
The committed ICS55 SRAM models are downloaded and verified by the PDK setup
flow from the dependency lock; no local commercial SRAM path is needed.
HAVE_SRAM_MACRO=YES requires HAVE_SRAM_IF=YES. The generic manual defaults
enable 32 KiB for IHP130, GF180, SKY130, and ICS55; committed profiles remain
the supported reproducible entry points.
PDK_BEHAV=YES selects technology-wrapper functional models for behavioral
simulation. It is a simulation-only setting, participates in the build variant
key, and is invalid with Yosys synthesis. Profiles that execute from an SRAM
macro must select either this mode or a qualified macro timing model.
For supported profiles and commands, see the root README and agent contract.
Tiny MCU
benchmark/ics55-tiny-performance.mk is the separate R2-P3 compiler experiment
entrypoint: the same SAFE24/parked-PLL hardware, validated candidate ISA,
SW_OPT=O2 and SW_LTO=NO. Optimizer/LTO and ld2_tiny_banked placement are
explicit variants; the CI profile remains compatible RV32IM. See the
software scheduling runbook
for the matrix and its pending/current evidence boundary.
The 2026-10-07 Tiny refreeze
sets the default to ICS55 with HAVE_PLL=YES and SAFE24 boot.
ci/ics55-tiny.mk boots with the PLL held off; R2-P7 adds explicit software
requests for functional PLL192/240 transitions, subject to separate acceptance.
ci/ihp130-tiny-xin48.mk and ci/ihp130-tiny-xin96.mk normalize their declared
external input to REF24 at boot and permit no-PLL XIN transitions. See the
P7 runbook for the evidence boundary.
TINY_P7_ACCEPTANCE=YES APP=ci_smoke selects the distinct RCU acceptance image
and configuration digest; ordinary Tiny acceptance firmware remains the default.
TINY_P8_ACCEPTANCE=YES APP=ci_smoke instead selects the optional XPI PSRAM
transport image and its distinct digest. Populate the verification device with
TINY_SIM_ARGS=+tiny_p8_psram; P7/P8/P9 acceptance selectors are mutually exclusive.
See the P8 runbook for bounded DMA and evidence.
TINY_P9_ACCEPTANCE=YES APP=ci_smoke selects the DVP camera capture image;
use TINY_SIM_ARGS='+tiny_psram +tiny_p9_camera' for the pin-level camera
model. The optional TINY_P9_QUICK=YES selector is a small focused smoke image,
not QVGA/VGA acceptance. See the P9 runbook.
TINY_P9_WORKLOAD=VGA_YUV422 selects the full 640x480 YUV422 image and
changes its configuration digest. It requires P9 acceptance with QUICK=NO;
the default QVGA_RGB565 retains the existing configuration key. Pair the
VGA image with +tiny_p9_vga; mismatched source geometry is not acceptance.
For passive progress add +tiny_p9_monitor +tiny_p9_monitor_log=<absolute-evidence-file>;
the separate log preserves firmware UART record boundaries.
make SOC=TINY selects this
committed profile, and make SOC=TINY PDK=IHP130 selects explicit compatibility.
Do not substitute Mini's ci/ics55.mk for Tiny. Acceptance evidence belongs in
the Tiny ledger, and physical qualification remains pending.
ci/ihp130-tiny.mk selects SOC=TINY, one RV32IMC Hazard3 (A disabled),
128 KiB SRAM and AXI32/APB4. The P6 candidate adds eight-channel DMA and the
frozen shared-peripheral integration; source presence is not phase acceptance.
The profile uses 24 MHz, HAVE_HP=NO, MINI_MODE=NONE, CSR-enabled RV32IM
firmware and ld2_all_sram. Both bringup and ci_smoke select Tiny acceptance
firmware. Icarus and Verilator use the same pin-level Flash model. PDKs other
than IHP130/ICS55, external-RAM boot layouts and HP applications remain rejected.
