Embodiment 1
[0042] refer to Figure 1~Figure 4 , this optical feedback strategy based on MSD adder is characterized by separating the three-step MSD addition steps and implementing it in a pipelined manner; when the first set of data completes T and W operations and is about to enter T' and W' operations, The second group of data enters into T and W operations, the first group of data enters into T2 operations, the second group of data enters into T' and W' operations, the third group of data enters into T and W operations, and so on until all data operations are completed; Combined with the system structure of the MSD adder, data feedback is performed during the addition process, that is, the operation results of T, W are fed back to the code storage space of the T', W' calculator, and the operation results of T', W' are fed back to the T2 operation In the encoding storage space of the device, it is used as the encoding information for the next operation, so that the adder can run contin...
Embodiment 2
[0044] This embodiment is basically the same as Embodiment 1, and the special features are as follows:
[0045] The operation steps of the data feedback strategy are as follows:
[0046] 1) According to the mapping relationship between the three light states of each operator and the encoding information, the decoding result is converted into the corresponding encoding information, and the encoding information string is combined into bits;
[0047] 2) Store the respective encoded information strings in the memory according to the base address and offset address of T, W, T', W', and T2 calculators respectively;
[0048] 3) The data in the storage space of the T, W, T', W' calculators is filled with 0 in the intermediate results;
[0049] 4) Carry out data communication; and transmit the encoded information string in the storage space of the T2 calculator to the host computer client through network communication, and clear the data information in the storage space after the tran...
Embodiment 3
[0059] figure 1 It is the structure of the MSD adder of the ternary optical computer, which is located between the encoder and the decoder of the ternary optical computer. It includes the first logic operation unit, the second logic operation unit, the third logic operation unit, ARM development board, the first logic operation part is composed of the first liquid crystal, the first front and rear polarizers, and the first photosensitive array, and is used to simultaneously complete the T operation and W operation involved in the input optical path; the second logic operation part is composed of the second Composed of liquid crystal, the second front and rear polarizers, and the second photosensitive array, it is used to simultaneously complete the T' operation and W' operation involved in the input optical path; the third logical operation part is composed of the third liquid crystal, the third front and rear polarizers , The third photosensitive array is used to complete th...
