The following block declarations are made in the platform descriptor file. They represent hardware resources available on the hardware platform.
AudioIn is a signal block bundle defined in the platform descriptor file. It enables access to the audio input hardware resources available on the hardware platform.
The audio stream output port values are between +/- 1.0.
# AudioIn declaration, where 'SIZE' represents the number of available audio inputs
signal AudioIn [SIZE] {
default: 0.0
rate: AudioRate
reset: MasterReset
meta: 'Audio Input'
}
_audioCODEC_x >> AudioIn[x];
AudioOut is a signal block bundle defined in the platform descriptor file. It enables access to the audio output hardware resources available on the hardware platform.
The audio stream input port accepts values between +/- 1.0. Values outside this range are clipped.
#AudioOut declaration, where 'SIZE' represents the number of available audio outputs
signal AudioOut [SIZE] {
default: 0.0
rate: AudioRate
reset: MasterReset
meta: 'Audio Output'
}
AudioOut[x] >> _audioCODEC_x;
AudioRate is a constant block defined in the platform descriptor file. It holds the sampling rate value of the audio CODEC.
#AudioRate declaration
constant AudioRate {
value: 48000
meta: 'Sampling rate of audio ADCs and DACs (Hz)'
}
ControlIn is a signal block bundle. It enables access to the analog input hardware resources available on the hardware platform.
#ControlIn declaration, where 'SIZE' represents the number of available analog inputs
signal ControlIn [SIZE] {
default: 0.0
rate: ControlRate
reset: MasterReset
meta: 'Analog Input'
}
_analogADC_x >> ControlIn[x];
AudioOut is a signal block bundle. It enables access to the analog output hardware resources available on the hardware platform.
#ControlOut declaration, where 'SIZE' represents the number of available analog outputs
signal ControlOut [Size] {
default: 0.0
rate: ControlRate
reset: MasterReset
meta: 'Analog Output'
}
ControlOut[x] >> _analogDAC_x;
ControlRate is a constant block defined in the hardware descriptor file. It holds the sampling rate value of the analong analog-to-digital and digital-to-analong converters.
# ControlRate declaration
constant ControlRate {
value: 2048
meta: 'Sampling rate of analog ADCs and DACs (Hz)'
}
DigitalIn is a switch block bundle. It enables access to the digital input hardware resources available on the hardware platform.
#DigitalIn declaration, where 'SIZE' represents the number of available digital inputs
switch DigitalIn [Size] {
default: off
reset: MasterReset
meta: 'Digital Input Pin'
}
_digitalInputPin_x >> DigitalIn[x];
DigitalOut is a switch block bundle. It enables access to the digital output hardware resources available on the hardware platform.
#DigitalOut declaration, where 'SIZE' represents the number of available digital outputs
switch DigitalOut [Size] {
default: off
reset: MasterReset
meta: 'Digital Output Pin'
}
DigitalOut[x] >> _digitalOutputPin_x;
Master reset switch for all signal and switch blocks.
switch MasterReset {
value: off
meta: 'Default master reset for all blocks'
}
