Rotation time de-interleaving circuit and operation method of convolution time de-interleaving circuit

The invention provides a convolution time deinterleaving circuit and an operation method of the convolution time deinterleaving circuit. The convolution time deinterleaving circuit comprises an input buffer circuit, an output buffer circuit, a memory, an input control unit, an output control unit and a controller. The memory includes a plurality of memory blocks. The input control unit sequentially and correspondingly writes a plurality of input data into a plurality of groups of input temporary storage units in the input buffer circuit. The controller writes part of data in the input buffer circuit into the corresponding memory blocks after writing a preset number of data into the input buffer circuit, and writes data stored in the corresponding memory blocks into the output buffer circuit after writing data into a plurality of memory blocks of the memory. The output control unit sequentially outputs a plurality of output data stored in the plurality of groups of output temporary storage units in the output
