3.1.3.1. Using Less Than 36-bit Operand In 18 × 18 Plus 36 Mode
This example shows how to configure the Arria 10 Native Fixed Point DSP IP core to use 18 × 18 Plus 36 operational mode with a signed 12-bit input data of 101010101010 (binary) instead of a 36-bit operand.
- Set Representation format for bottom multiplier x operand: to signed.
- Set Representation format for bottom multiplier y operand: to unsigned.
- Set 'bx' input bus width to 18.
- Set 'by' input bus width to 18.
- Provide data of '111111111111111111' to bx input bus.
- Provide data of '111111101010101010' to by input bus.
