Embodiment Construction
[0034] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0035] Inverse Block Mapping and Multiplexing Computational Upsampling Methods for Neural Network Accelerators mentioned in the design. In the block mapping, different block mappings are not exactly the same at the four adjacent pixels of the input feature map, and data multiplexing is used for the same part, so there will be no repeated reading.
[0036] like figure 1 As shown, an upsampling reverse block mapping method includes the following steps:
[0037] Step 1: According to the agreed method, read part of the data of the feature map and store it in the shift buffer.
[0038] like Figure 2-4 As shown, for data multiplexing, the input feature map cache ...
