ACT-SHAVE

ACT-SHAVE is DSP Processor which supports 128 bit vector operations. Two of ACT-SHAVE DSPs are placed in each NCE Tile and are used for custom layer and standard layers that do not map well to the DPU. All ACT-SHAVE DSP functions shall be included in the graph-file and barriers shall be used for HW Synchronization of the DSP operation and the rest of the schedule.

The features in ACT-SHAVE include:

  • BF16 load/store support, that is, load BF16 to FP32 and store FP32 to BF16
  • tanh, sigmoid and exp vector operations in FP16
  • FP16 denorm support where FP16 that may have subnormal values can be loaded into FP32 while retaining the subnormal values
