Classification: CPC G  Y | IPC G

Claim 3:
4. The eDRAM-based CIM CNN accelerator according to claim 1, wherein the 5T1C ping-pong eDRAM bit cell supports an intra-image parallel convolution mode and an inter-image parallel convolution mode;
in the intra-image parallel convolution mode, the 5T1C ping-pong eDRAM bit cell segments and convolves a same picture, an ABL 1 corresponding to one activation value input terminal obtains a convolution operation result of a pixel or an activation value of an upper half of the picture, and an ABL 2 corresponding to another activation value input terminal obtains a convolution operation result of a pixel or an activation value of a lower half of the picture; and
in the inter-image parallel convolution mode, an ABL 1 corresponding to one activation value input terminal obtains a convolution operation result of a first picture, and an ABL 2 corresponding to another activation value input terminal obtains a convolution operation result of a second picture.
