Monthly summary for 2025-10: Delivered initial ARM int8 Convolution and Quantization support in openvino. Key backend refactors and quantization config updates prepared for efficient ARM inference. Note limitations: s32 bias support only; i8/u8 output only. Impact centers on enabling on-device int8 inference on ARM/ARM64 and laying groundwork for broader quantized inference.

May 2025: Focused on stabilizing Eltwise fusion behavior in OpenVINO CPU/ARM path by hardening precision checks with Convert node. Delivered a targeted bug fix and regression test to prevent incorrect fusion when Convert precision is not f16 or f32, improving inference reliability across devices.

April 2025: ARM-focused OpenVINO improvements delivering correctness and performance gains. Implemented JIT Eltwise precision safety for ARM (restricting EltwiseDivide and EltwiseFloor to fp32/fp16 when fused with certain ops) and upgraded ACL to 25.03 with 2D parallelization in ACLScheduler to enable 2D splits. The changes improve ARM reliability and throughput, reduce edge-case failures, and position OpenVINO for higher ARM workloads.

March 2025 performance-focused month for the aobolensk/openvino repository. Highlights include ARM-optimized Low Precision Transformations (LPT) with FQ decomposition, maintenance of KleidiAI integration (GitHub relocation and licensing updates), and a precision-handling refactor to apply foldConvert unconditionally for constants in FuseMultiplyToFakeQuantizeTransformation and FuseSubtractToFakeQuantizeTransformation. These efforts improve ARM performance and compatibility, increase dependency stability and license accuracy, and strengthen test coverage for quantization flows. Overall, the changes deliver tangible business value by accelerating AI workloads on ARM devices, reducing licensing risk, and improving reliability of the quantization pipeline.
