ALTMULT_ADD Ports

Table 6-4: ALTMULT_ADD IP Core Input Ports

Port Name Required Description

dataa[] Yes Data input to the multiplier. Input port [NUMBER_OF_

MULTIPLIERS * WIDTH_A - 1..0] wide.

datab[] Yes Data input to the multiplier. Input port [NUMBER_OF_

MULTIPLIERS * WIDTH_B - 1..0] wide.

clock[] No Clock input port [0..3] to the corresponding register. This port

can be used by any register in the IP core.

aclr[] No Input port [0..3]. Asynchronous clear input to the

corresponding register.

ena[] No Input port [0..3]. Clock enable for the corresponding clock[]

port.

signa No Specifies the numerical representation of the dataa[] port. If the

signa port is high, the multiplier treats the dataa[] port as a

signed two's complement number. If the signa port is low, the

multiplier treats the dataa[] port as an unsigned number.

signb No Specifies the numerical representation of the datab[] port. If the

signb port is high, the multiplier treats the datab[] port as a

signed two's complement number. If the signb port is low, the

multiplier treats the datab[] port as an unsigned number.

Table 6-5: ALTMULT_ADD IP Core Output Ports

Port Name Required Description

result[] Yes Multiplier output port. Output port [WIDTH_RESULT -

1..0] wide.

overflow No Overflow flag. If output_saturation is enabled, overflow

flag is set.
