DSP & Algorithms

Algorithms come in many forms, and for many purposes; from digital signal processing of data from some form of sensor, highly mathematic computations for calculation, to cryptography including encryption, authentication and data integrity checking. For digital signal processing applications a typical algorithm development path would be:

  • Definition of the use cases for the system/function under consideration.
  • Modelling of system inputs (typically in Matlab) and/or initial collection of sample input data.
  • Creation of initial algorithmic models (typically in Matlab).
  • Initial algorithm implementation on prototype, commonly as floating point, sometimes used for demo.
  • Further data collection and algorithm improvement.
  • Target implementation of algorithm; typically initially in floating point, often with MEX wrapper to enable direct comparison/validation against original Matlab model.
  • Algorithm optimisation, if required (dependent on application and target); this may include
    • Reducing computation complexity (typically including fixed-point implementation including performance versus complexity trade-offs; often required for low-power operation
    • optmisation for processing speed (for time-critical operation)
    • optimisation to minimise ROM/RAM use (typically for implementation on a low-resource target)

Matlab modelling

Edenprime has broad experience of such algorithm development and implementation; Examples of work include:

Analysis of seismic signals for detection of nearby activity with source-type discrimination (algorithm development and fixed point implementation)

Implementation of optimised cryptographic authentication functions on ultra-low resource target to meet time and resource constraints

Analysis of motion and position sensor data for detection of significant fault events in critical infrastructure (algorithm development and fixed point implementation)

Implementation of Digital Pre-Distortion for high-speed antenna waveforms.

Implementation of optimised logarithm, exponential and geometric function libraries for particular low resource targets
