An integrated circuit comprising a plurality of multiplier-accumulator circuits connected in series in a linear pipeline to perform a plurality of concatenated multiply and accumulate operations, wherein each multiplier-accumulator circuit of the plurality of multiplier-accumulator circuits includes: a multiplier to multiply first data by a multiplier weight data and generate a product data, and an accumulator, coupled to the multiplier of the associated multiplier-accumulator circuit, to add second data and the product data of the associated multiplier to generate sum data. The integrated circuit also includes a plurality of granularity configuration circuits, wherein each granularity configuration circuit is associated with a different multiplier-accumulator circuit of the plurality of multiplier-accumulator circuits to operationally (i) disconnect the multiplier and accumulator of the associated multiplier-accumulator circuit from the linear pipeline during operation or (ii) connect the multiplier and accumulator of the associated multiplier-accumulator circuit to the linear pipeline during operation.
