  "message": "Rewrite RISP4ML in plain-C for Shodan\n\nThis CL is Part 1 of the comprehensive 3-part changes of integrating RISP4ML into Shodan ML toolchain. This change focuses on re-writing RISP4ML in plain-C.\n\nPart 2 and 3 will be submitted after this CL is merged (codes can be\nseen at Patch Set #13).\n\nDetails of the 3-part changes:\n\n(Part 1) Completely re-wrote RISP4ML in plain C.\n- The original RISP4ML on google3 was written in C++. The memory usage with C++ RISP4ML was significantly larger. Thus, I have completely re-written RISP4ML in plain C. The memory increase with the plain-C RISP4ML is much smaller.\n- Made the input/output shape to be configurable arguments instead of constants.\n- Made low-level optimizations and simplifications.\n\n(Part 2) Integrated plain-C RISP4ML into Shodan ML toolchain\n- Use fssd_25_8bit_v2 as an example to load the binary (raw bayer) file and go through RISP4ML toolchain, and feed the RISP4ML output into IREE flow.\n- The fssd_25_8bit_v2 example is up and running, and the correctness of output has been verified (compare output@plain-C risp4ml against output@google3).\n\n(Part 3) Added unit tests for plain-C RISP4ML\n- Added unit tests based on pw_unit_test\n- Build unit tests in iree_cc_binary\n- Run and check unit tests via lit_test\n\nChange-Id: Id17dd01fd3848d9705b8b39ea2866bde3334613c\n",
