From dsp macro /usr/lib/dsp/ugsrc/scl2add2.asm (see source for details). 00007 00008 You instantiate a subclass of the form Scl2add2UG<a><b><c>, where 00009 <a> = space of output 00010 <b> = space of input1 00011 <c> = space of input2 00012 00013 The scl2add2 unit-generator multiplies two input signals 00014 times constant scalers then adds them together to produce a 00015 third. The output vector can be the same as an input vector. 00016 Inner loop is two instructions if space of input1 is "x" and 00017 space of input2 is "y", otherwise three instructions. 00018 00019 Original Author: David A.
