feldspar-language-0.6.0.2: A functional embedded language for DSP and parallelism

Safe Haskell | None

Feldspar.Vector

Description

A module for virtual vectors. Many of the functions defined here are imitations of Haskell's list operations, and to a first approximation they behave accordingly.

A virtual vector is normally guaranteed not to be present in the generated code. The only exceptions are:

- when it is explicitly forced using the functions `force` or `desugar`
- when it is the input or output of a program
- when it is accessed by a function outside the Feldspar.Vector API, for example, `condition` or `forLoop`

Note also that most operations only introduce a small constant overhead on the vector. The exceptions are

- `fold`
- `fold1`
- Functions that introduce storage (see above)
- "Folding" functions: `sum`, `maximum`, etc.

These functions introduce overhead that is linear in the length of the vector.
