Embodiment Construction
[0050] In order to improve the problem that the traditional fixed-bit-width CSD multiplier cannot take into account accuracy, power consumption and speed, the invention designs a low-bit compensation circuit with high precision, adopts a simple circuit structure, reduces the hardware overhead of the whole circuit, and improves the multiplication rate. the operating speed of the device. The low-order compensation structure of the present invention can be operated in parallel with the partial product compression circuit to a certain extent, which further improves the operation speed of the overall circuit;
[0051] This example works as follows:
[0052] This example is mainly divided into four main circuit parts, CSD coding circuit, high-order partial product generating circuit, low-order compensation circuit and partial product compression circuit.
[0053] The CSD encoding circuit uses an iterative serial structure such as figure 2 and image 3 As shown, its logical expre...
