(8.D.2.1) MultiplierV2Fract32
- Catherine Spain
Overview
Multi-purpose multiplier
Discussion
Multi-purpose multiplier module. For single channel inputs, all of the inputs will be multiplied together. For multichannel inputs, the ONECHANNELOUTPUT argument determines whether all of the channels in each input will be multiplied together (ONECHANNELOUTPUT=1), or whether a given channel in one input will be multiplied by the corresponding channel in another input (ONECHANNELOUTPUT=0). If oneChannelOutput is false and there are only 2 input pins and first input has only 1 channel, then all other channels are multiplied by the first input channel.
Type Definition
typedef struct _ModuleMultiplierV2Fract32
{
ModuleInstanceDescriptor instance; // Common Audio Weaver module instance structure
INT32 multMode; // multMode=0 is a multi-input multiplier, multMode=1 is an AGC multiplier
INT32 oneChannelOutput; // Boolean value that determines whether all channels are multiplied to form a single output.
INT32 postShift; // Number of bits to shift

File Name: multiplier_v2_fract32_module.m
M=multiplier_v2_fract32_module(NAME, NUMINPINS, ONECHANNELOUTPUT)
Creates a multi-purpose multiplier module for use in the Audio Weaver
Environment. Can also function as a multi-input multiplier or an AGC
multiplier. Mode of operation is determined by the number of input
pins/channels.
Arguments:
NAME - name of the module.
NUMINPINS - number of input pins.
ONECHANNELOUTPUT - Boolean value which determines if multi-channel
input signals are collapsed to a single output channel.Â
