v7.23.0

7.23.0 (2026-04-10)

Features

• add arm_sqrt_s16 kernel with MVE-optimized path (af1429c)
• add arm_sqrt_s16 kernel with MVE-optimized path (3c97bcd)
• add depthwise fast path to arm_convolve_wrapper_s16 (45d68a3)
• add int16 rsqrt kernels and generated tests (5b4e8ac)

Bug Fixes

• add arm_convolve_s16_depthwise.c to PDSC (c78ce6b)
• add arm_sqrt_s16.c to PDSC source file listing (2e87b7e)
• depthwise scalar path uses arm_nn_requantize for int32 bias, add uint16 offset overflow guard (932650a)
• remove unnecessary casts discarding const from LUT pointers (576da80)

Refactoring

• remove duplicate static helper, call arm_convolve_s16_group_ch_mult_1 from wrapper (73679b3)
• rename arm_convolve_s16_depthwise to arm_convolve_s16_group_ch_mult_1 (03b2f86)
