Parameter IP Generated Parameter Value Description
‘ax' operand source operand_source_max

input

coef

Specify the operand source for ax input bus. Select coef to enable internal coefficient module for top multiplier.

Select No for Register input 'ax' of the multiplier parameter when you enable the internal coefficient feature.

Settings for ax and bx operand source must be the same.

'bx' operand source operand_source_mbx

input

coef

Specify the operand source for bx input bus. Select coef to enable internal coefficient module for top multiplier.

Select No for Register input 'bx' of the multiplier parameter when you enable the internal coefficient feature.

Settings for ax and bx operand source must be the same.

'coefsel' Input Register Configuration
Register input 'coefsela' of the multiplier coef_sel_a_clock No

Clock0

Clock1

Clock2

Select Clock0, Clock1 or Clock2 to enable and specify the input clock signal for the coefsela input registers.
Register input 'coefselb' of the multiplier coef_sel_b_clock No

Clock0

Clock1

Clock2

Select Clock0, Clock1 or Clock2 to enable and specify the input clock signal for the coefselb input registers.
Coefficient Storage Configuration
coef_a_0–7 coef_a_0–7 Integer Specify the coefficient values for ax input bus.

For 18-bit operation mode, the maximum input value is 218 - 1. For 27-bit operation, the maximum value is 227 - 1.

coef_b_0–7 coef_b_0–7 Integer Specify the coefficient values for bx input bus.
