v24.11

v24.11 Public Major Release

Feat

• Add SVE SoftmaxLayer kernel for BF16
• Provide stateless API for CpuGemmLowpMatrixMultiplyCore, CpuQuantize, and DequantizationLayer
• Extend static quantization interface for both matmul and convolution operations

Fix

• Clarify Third-Party IP licenses
• Check if CpuGemmAssemblyDispatch is configured in CpuMatMul before continue
• Add BF16 support for CpuGemmAssemblyDispatchWrapper
• Detect SVE support on Windows® to run the available kernels

• Disable -O2 when building for Windows® as this crashes when certain compiler versions are used
• Make cast on CPU truncate float to int instead of round to be consistent with other ML frameworks
• Return error in validate() for CpuGemmLowpMatrixMultiplyCore if pretransposed A or B are true as this is not supported
• Avoid implicit conversion from __fp16 to arm_compute::bfloat16 to avoid illegal instructions in hardware with FP16 but no BF16 support
• Softmax SME2 kernel selection now correctly detects if SME2 is supported
• Requantization rounding issues in CPU/GPU Quantize
• Scale normalising coefficient in GPU LogSoftmax
• Apply consistent rounding policy in NEReduceMean
• Revert default memory manager for NEQLSTMLayer
• Create default memory manager when none is provided

Refactor

• Turn duplicated code in the elementwise_binary kernel into templates to reduce code size
• Move CpuSoftmaxKernel LUT to LUTManager to consolidate location of all LUTs

Perf

• Use SME instead of SVE for subtractions in SoftmaxLayer for Q8 relating to LUT address calculation
