A DSP toolbox with focus on embedded environments.
Signalo provides the basic building-blocks for low-level real-time filtering pipelines,
based on zero-cost, zero-allocation abstractions, which can be assembled via composition.
Signalo basically consists of five basic traits and implementations thereof:
Source<T>:() -> TFilter<T>:T -> UMultirateFilter<T>:(&[T], &mut [U]) -> (usize, usize)Sink<T>:T -> ()Finalize:() -> U
Roughly signalo's traits are equivalent in semantics to the following stdlib APIs:
Source<…>≈core::iter::Iterator<…>Filter<…>≈core::iter::Map<…>Sink<…> + Finalize≈Iterator::fold(…)Filter<…> + Finalize≈core::iter::Scan<…>
MultirateFilter<T> has no direct stdlib iterator equivalent because input
and output progress can differ on each call.
Types implementing Finalize usually also implement either Filter<T> or Sink<T>.
Signalo provides the basic building-blocks for low-level real-time filtering pipelines, which can be assembled via composition either manually or through the use of pipes.
This crate can be used without the standard library (#![no_std]) by disabling the default std feature. Use this in Cargo.toml:
[dependencies.signalo]
version = <VERSION>
default-features = false
# features = ["libm"] # <- Uncomment if you wish to use float math functions without `std`We use SemVer for versioning. For the versions available, see the tags on this repository.
