Description

technical field [0001] The invention relates to a multiplication accumulator, in particular to a configurable and expandable pipeline multiplication accumulator. Background technique [0002] Digital signal processing is the theory and technology of representing and processing signals in digital form. As an extremely important technical means in today's society, it is widely used in various engineering and technical fields. In recent years, with the development of science and technology, it is also known as one of the theoretical foundations of emerging disciplines such as artificial intelligence, and its importance and wide application are self-evident. [0003] In system applications, the realization of almost all complex algorithms is inseparable from the multiply-accumulate operation unit, such as FIR, FFT, up-down frequency conversion and other algorithms can be realized by the multiply-accumulate operation unit. In programmable logic devices, the multiplication and ac...

Problems solved by technology

[0005] Aiming at the above existing problems, the present invention provides a configurable and expandable pipelined multiply-accumulator to overcome the problem that the structural design of the multiplier-accumulator in the prior art is relatively complicated and the cost is high, and also to overcome the multiplier-accumulator in the prior art. The problem of low operation speed and efficiency of the accumulator, so that on the basis of ensuring the operation functions of different bit widths, it can realize the operation functions such as multiplication, multiplication and addition, and multiplication and accumulation. At the same time, it has a compact structure, flexible expansion, and user-configurable. Computing speed and efficiency are also greatly improved
