Computes both the sine and cosine of a specified value (x). You must specify x in pi radians, which use fewer FPGA resources than radians. To convert a radian value to pi radians, multiply the value by pi.

x

An input to this operation.

input valid

A Boolean that describes whether the next data point has arrived for processing. Wire the output valid output of an upstream node to this input to transfer data from the upstream node to this node.

 TRUE The next data point has arrived for processing. FALSE The next data point has not arrived for processing.

A Boolean that specifies whether downstream nodes are ready for this node to return a new value. Use a Feedback Node to wire the ready for input output of a downstream node to this input of the current node.

 TRUE The downstream node is ready for the next data point. FALSE The downstream node is not ready for the next data point. Note   If this terminal is FALSE during a given cycle, the output valid terminal returns FALSE during that cycle.

Default: TRUE

sin(x)

Result of the operation in pi radians, which uses fewer resources on the FPGA.

This output assumes the same numeric representation as x. When x is of the form x = a + b i, that is, when x is complex, the following equation defines sin:
$\mathrm{sin}\left(x\right)=\mathrm{sin}\left(a\right)*\mathrm{cosh}\left(b\right)+i\left(\mathrm{cos}\left(a\right)*\mathrm{sinh}\left(b\right)\right)$

cos(x)

Result of the operation in pi radians, which uses fewer resources on the FPGA.

This output assumes the same numeric representation as x. When x is of the form x = a + b i, that is, when x is complex, the following equation defines cos:
$\mathrm{cos}\left(x\right)=\mathrm{cos}\left(a\right)*\mathrm{cosh}\left(b\right)+i\left(-\mathrm{sin}\left(a\right)*\mathrm{sinh}\left(b\right)\right)$

output valid

A Boolean that indicates whether this node has computed a result that downstream nodes can use. Wire this output to the input valid input of a downstream node to transfer data from the node to the downstream node.

 TRUE The node has computed a result that downstream nodes can use. FALSE The node has not computed a result that downstream nodes can use.
