<p>A system, such as e.g. a multiplier, for processing digital signals by using digital signals (x) in the Canonic Signed Digit (CSD) representation includes: an input element (10) configured for making the digital signals (x) available in the Binary Canonic Signed Digit (BCSD) representation, a converter (20) for converting the digital signals made available in the Binary Canonic Signed Digit (BCSD) representation into said Canonic Signed Digit (CSD) representation in view of use in processing. The input element (10) may be a memory where the signals are stored in the Binary Canonic Signed Digit (BCSD) representation. Alternatively, the input element is adapted to be fed with digital signals (x) in the two's complement representation, and includes at least one converter (10) for converting the digital signals from the two's complement representation into the Binary Canonic Signed Digit (BCSD) representation. This preferably occurs via the T2I transformation, which leads to generating signals in the Canonic Signed Digit (CSD) representation, which are then converted to the Binary Canonic Signed Digit (BCSD) representation.</p> |
