Problems solved by technology
However, existing data processors can only perform multiplication and accumulation operations on data with the same bit width, which reduces the versatility of the data processor
In addition, in the prior art, multiple multiplication results need to be accumulated separately to realize the multiplication and accumulation operation, thereby increasing the power consumption of the data processor

The invention provides a data processor, a method, a device and a chip. The data processor comprises a first multiplication circuit, a second multiplication circuit and a partial product switching circuit, the first multiplication circuit comprises a first improved regular signed number CSD coding branch, a first selection branch and a first improved compression branch, The second multiplication circuit comprises a second improved CSD coding branch, a second selection branch and a second improved compression branch; Each of the first improved compression branch and the second improved compression branch comprises a 4-2 compressor, and each 4-2 compressor comprises a selection circuit and a full adder; The data processor not only can realize multiplication operation, but also can realize multiply-accumulate operation, so that the universality of the data processor is improved; Besides, the data processor can complete the multiply-accumulate operation without carrying out the accumulate operation on the multiplication operation result again, and the multiply-accumulate operation or the multiplication operation can be directly realized only through one operation process, so that the power consumption of the data processor is reduced.
Description
Technical field [0001] The present application relates to the field of computer technology, and more particularly to a data processor, method, apparatus, and chip. Background technique [0002] With the continuous development of digital electronic technology, the rapid development of all kinds of artificial intelligencers (AI) chips is also increasing in high performance data processors, of which data processors are multipliers, adders or multiplication accumulator. As one of the algorithms widely applied by the intelligent chip, the neural network algorithm is used by multipliers to multiply the intensive accumulation operation in a neural network algorithm. [0003] Typically, the data processor is a multiplier multiplier that uses multiple identical input data bit wide or different data bit wide, and obtains multiple multiplication operations, and then the plurality of multiplier calculations are accumulated by the plurality of multiplication results. Target multiplication res...
