FIXPIPEFUSIONPASS

Description

On hardware with FIXPIPE support, when a cube operator has the support_fixpipe_ability attribute configured in FixPipeAbilityProcessPass, it will sequentially attempt to match the convert, activation, and transform units as shown in the figure below. If at least one of these units exists (nonexistent units are skipped), the matched units will be fused into a FIXPIPE operator.

• convert unit: format conversion unit, which is usually a quant or cast operator.
• activation unit: activation unit, which is usually a ReLU operator.
• transform unit: format conversion unit for converting ND to NZ, which is usually a TransData operator.

Restrictions

• Only static networks are supported.
• This fusion pattern cannot be disabled.
