Abstract
An integrated circuit including a plurality of logarithmic addition-accumulator circuits, connected in series, to, in operation, perform logarithmic addition and accumulate operations, wherein each logarithmic addition-accumulator circuit includes: (i) a logarithmic addition circuit to add a first input data and a filter weight data, each having the logarithmic data format, and to generate and output first sum data having a logarithmic data format, and (ii) an accumulator, coupled to the logarithmic addition circuit of the associated logarithmic addition-accumulator circuit, to add a second input data and the first sum data output by the associated logarithmic addition circuit to generate first accumulation data. The integrated circuit may further include first data format conversion circuitry, coupled to the output of each logarithmic addition circuit, to convert the data format of the first sum data to a floating point data format wherein the accumulator may be a floating point type.
