Description

This block is a binary adder with carry output. With a feedback from the carry to one of input, one can realize an accumulator with this block.

Dialog box

• Number of bits
  Number of bits of the internal registers.
  Properties : Type 'vec' of size 1.

• Output type
  Output data type
  • 1 double

  • 3/4/5 int32/int16/int8

  • 6/7/8 uint32/uint16/uint8

Default properties

• always active: no
