Abstract (en)
[origin: WO2005024542A2] The invention relates to a digital signal processing device comprising: input storage means (3; 5); a computational device (4) that is connected to said means, defines a data path (9) and contains at least one arithmetic unit (6) in addition to a control input (2a) for specifying calculation operations; and output storage means (8). The data path (9) between the arithmetic unit (6; 7) and the output storage means (8) is equipped with a number-format conversion unit (10) comprising a shift unit (17). A number-format specification unit (11) and a control unit (17'), which is connected to the latter and calculates required shift operations on the basis of the number-format specification, are assigned to the number-format conversion unit (10). Formatting operations are calculated automatically using input and output format information and corresponding commands are applied to the shift unit (17).
