More Information
Summary:The invention provides an MAC (Media Access Control) array for data calculation, which comprises a plurality of array units, and each array unit comprises a plurality of sub-MAC modules, a first shifter and a first summator; wherein the first end of the first sub-MAC module is connected with the first end of the first summator, the first end of the second sub-MAC module is connected with the first end of the first shifter, the second end of the first shifter is connected with the second end of the first summator, and the output end of the first summator serves as the output end of the array unit; the first shifter is used for realizing shifting of output data of the second sub-MAC module; and the first adder is used for adding the output data of the first sub-MAC module and the output data of the first shifter. Therefore, the MAC array supports the mixed precision data format through splitting and shift accumulation of the data, so that the MAC array can be configured according to the target data format, and
