Output
Specify the number of bits to the left of the binary point of all input
signals.
The number of coefficients.
Specify the number of bits to the left of the binary point of all non-variable
coefficients represented as a signed integer.
Specify the coefficient values for each port as a sequence of signed
integers.
For example: [-587 -844 -678 -100 367 362 71 -244]
Specify the number of pipeline stages.
When on, the multiplier output bit width is full resolution. When off, you
can specify the number of bits in the output signal and the number of
least significant bits (LSBs) truncated from the output signal.
Specify the number of bits in the output signal.
Specify the number of LSBs to be truncated from the output signal.
Use a distributed arithmetic, dedicated multiplier or automatically
determined implementation.
Turn on to use the clock enable input (ena).
Turn on to use the asynchronous clear input (aclr).
Preliminary
1 to 8 ports corresponding to the signed integer fixed coefficient
values specified in the block parameters.
Optional clock enable.
Optional asynchronous clear.
