Abstract:
A computer system comprising:an input log converter for converting input data into a log domain;a number N of parallel computing units;a data pipeline having an input coupled to the input log converter, said data pipeline coupling the computing units so that data words can be shifted from one computing unit to the next;a memory having rows and at least a number N of columns, each of said computing units being assigned to a different one of said columns;a control unit being adapted to control the computer system so that to perform a first operation, each of said computing units accesses a memory location of a first row of said memory in its assigned column, and to perform a second operation interrupting said first operation, said data words in the data pipeline are buffered in a second row of said memory, wherein said control unit is adapted to control the computer system so that a sequence of first coefficients being representative of said first operation are stored in the first row, and a sequence of second coefficients being representative of said second operation are stored in a third row of said memory;an inverse log converter coupled to outputs of the computing units to convert a result obtained by a computing unit back to the normal domain; andan adder tree being coupled to the inverse log converter to sum the results in the normal domain.
