抄録

The demand for high-speed communication has been increasing in recent years. A data compression method that requires limited resources and has high speed is necessary for high-speed data communication. We proposed Logical Triangle Method to fulfil this requirement before this paper, which enables a codeword to be derived on demand by an operator. In this paper, we propose a new method of dynamically selecting the operator to improve its performance. Moreover, we evaluated its performance through simulation, which verified that It could achieve good data compression in bi-level image coding although this is one-dimensional coding. At the same time, we worked on implementing a sample encoder to a PLD and evaluated it on the device. As a result, we confirmed that our method could achieve high-speed coding with a small scale encoder.
