    Abstract: 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.

    Abstract translation: 一种系统，例如 用于通过使用数字信号（x）来处理数字信号的乘法器，其特征在于包括：输入元件（10），被配置为使数字信号（x）可用于二进制加拿大签名数字（BCSD） 考虑到在处理中的使用，转换器（20）用于将二进制加拿大签名数字（BCSD）表示中可用的数字信号转换成所述加拿大签名数字（CSD）表示。 输入元件（10）可以是其中信号被存储在二进制加拿大签名数字（BCSD）表示中的存储器。 或者，输入元件适于以二进制补码表示的数字信号（x）馈送，并且包括至少一个转换器（10），用于将来自二进制补码表示的数字信号转换成二进制加拿大签名数字（BCSD） 表示。 这优选地通过T2I变换发生，这导致在加拿大签名数字（CSD）表示中产生信号，然后将其转换为二进制加拿大签名数字（BCSD）表示。

    Abstract: A data processor unit (180), including at least two operation-execution units (PU1,..., PUn), each operation-execution unit being adapted to: receive input data (DX1,..DXn, DY1,..Dyn, DZ1,..DZn); perform a respective operation on the input data; and outputting output data (DO1,...,DOn) resulting from said input data after applying said operation, the data processor unit further including: a data storage unit ( 220 ) including at least two individually-accessible memory devices (B1,.., Bm) adapted to store data; a programmable controller ( 205 ) adapted to be programmed so as to execute a selected program; a first data routing circuit arrangement ( 225 ) adapted to receive data from the at least two memory devices, from the programmable controller and from a second data routing circuit arrangement ( 235 ), and for selectively routing selected ones among the received data to the input of the operation-execution units; said second data routing circuit arrangement being adapted to receive the output data outputted by the operation-execution units and to selectively route the output data to the at least two memory devices, to the programmable controller, and to the first data routing circuit arrangement; wherein the programmable controller is operatively coupled to the at least two operation-execution units, to the first and second data routing circuit arrangements, and to the at least two memory devices for controlling the operation thereof.
