Abstract: The subject matter hereof relates to error detection. Various example embodiments for error defection are disclosed. In an example method of error detection in a Module UnderTest (MUT), a parity signal representing the parity of an MUT output is compared to a parity signal representing the parity of an errorless MUT output. In an example system, an Actual Parity Generator provides a parity signal representing the parity of on MUT output, a State Parity Generator provides a parity signal representing the parity of an errorless MUT output, and a comparator compares these two parity signals.

Abstract: The invention relates to a digital system (1) and the method for error detection thereof. The digital system (1) comprises, as it's main core, a Module under Test (110) included in a Digital Processing Unit (100) and a State Parity Generator (SPG) (300). The SPG (300) is an equivalent with respect to parity of the Module under Test (300). An equivalent with respect to parity is a combinatorial circuit that, when an imput vector is applied at the imput of both Module under Test (110) and SPG (300), the output of the SPG (300) generates at it's output the parity of the transfer function of the Module under Test (110).

Abstract: Errors are corrected that occur in the operation of a combinatorial logic circuit in an integrated circuit.

Abstract: The invention relates to a multiplier for the multiplication of at least two figures in an original format. Each of said figures is fed to a first converter for conversion of each of said figures in the product of a first binary number representing a power of 2, and a second binary number representing a signed power of 3, the exponents of the powers of 2 of the concerning figures being fed to a first adder and the exponents of the powers of 3 of the concerning figures being fed to a second adder, whereby the combined respective outputs of the first adder and the second adder represent the multiplied value of said figures, and the resulting powers of 2 and 3 as available at the outputs of the first and second adder being fed to a second converter for conversion of the multiplied value into the original format.
