摘要:
A system, such as, e.g., a multiplier, for processing digital signals by using digital signals in the Canonic Signed Digit representation, the system including an input element to make the digital signals available in the Binary Canonic Signed Digit representation, a converter to convert the digital signals into Canonic Signed Digit representation for use in processing. The input element may be a memory where the signals are stored in the Binary Canonic Signed Digit representation. Alternatively, the input element is adapted to be fed with digital signals in the two's complement representation, and includes at least one converter to convert the digital signals from the two's complement representation into the Binary Canonic Signed Digit representation. This preferably occurs via the T2I transformation, which leads to generating signals in the Canonic Signed Digit representation, which are then converted to the Binary Canonic Signed Digit representation.
