BR/BI Operand Width
Select the second operand width. The width applies to both the real and imaginary components of the complex operand. See TDATA Structure for A, B and DOUT Channels to see how the operand components map into TDATA for this channel. This parameter is automatically updated in IP integrator.
Note: When the Floating Point data type is selected, this field is disabled and its value is fixed to 32 bits.
Has TLAST
Select whether the channel has TLAST. To ease system design, the core passes any TLAST and TUSER to the output with latency equal to the TDATA field. See TLAST and TUSER Handling.
Note: When the Has Accumulator option is enabled, at least on TLAST signal from either Channel A or Channel B must be active.
Has TUSER
Select whether the channel has TUSER. To ease system design, the core passes any TLAST and TUSER to the output with latency equal to the TDATA field. See TLAST and TUSER Handling.
TUSER Width
Select the width, in bits, of the TUSER field for this channel. This parameter is automatically updated in IP integrator.
Multiplier Construction Options
Allows the choice of using LUTs (slice logic) to construct the complex multiplier, or using DSP Slices.
Note: When the Floating Point data type is selected, this field is disabled and its value is fixed to DSP Slices.
Optimization Goal
Selects between Resource and Performance optimization.
  • This selection affects both the internal architectural decisions and the performance/resource trade-offs in the AXI4-Stream interfaces.
  • For Multiplier-based implementations, Resource optimization generally uses the three real multiplier structure. The core uses the four real multiplier structure when the three real multiplier structure uses more multiplier resources. Performance optimization always uses the four real multiplier structure to allow the best clock frequency performance to be achieved.
Flow Control Options
Selects between Blocking and NonBlocking behavior for the AXI4-Stream interfaces. See NonBlocking Mode and Blocking Mode for greater detail.
