01 / Dedicated processing

Designed around the work of sound.

Control and audio processing have distinct roles. Cortex-M0 configures parameters; the Router organizes the selected audio processing modules.

Matrix

64 × 64

Mix with precision.

4,096 floating-point weights map input channels into weighted output combinations.

FIR

32 cores

Allocate filtering resources.

Parallel FIR resources support different channel and tap combinations, including mixed profiles.

Delay

64 channels

Bring time into alignment.

Independent channel delay and gain compensation support audio time alignment.

Cortex-M0 / Router / Gain · Mute

One configurable audio path.

Routing connects selected processing resources; Matrix, FIR and Delay are not a mandatory serial sequence. Input and output gain and mute remain channel-controlled.

02 / FIR resources

Choose channels. Shape the filter.

32 parallel cores can be allocated across different channel and filter-length combinations. Explore the three uniform profiles listed in the datasheet.

Selected internal FIR configuration

64channels2048taps

Each of the 32 cores processes 2 channels at 2048 taps.

These values describe internal filtering resources. Physical TDM I/O stays at up to 64 input and 64 output channels.
