Title: Huffman encoder and decoder
Inventor: MATSUURA YOKO
IPC: H03M7/42
Filed: 1991-09-13
Abstract: PURPOSE:To send a Huffman code with less transmission quantity. CONSTITUTION:A probability calculation circuit 5 calculates the occurrence probability of an information source symbol fed from an information source 1. Occurrence probability sets P(C)-P(E) each being a small value are fed to an arithmetic operation circuit 6, in which they are summed. An arithmetic operation circuit 8 calculates a mean value of outputs of the arithmetic operation circuit 6 and outputs the result to a Huffman table generating circuit 7. The Huffman table generating circuit 7 generates a Huffman table based on occurrence probability sets P(A),P(B) fed from the probability calculation circuit 5 and transmission probability sets P1(C)-P1(E) fed from the arithmetic operation 8. A Huffman coder 3 references a Huffman table generated by the Huffman table generating circuit 7 to apply Huffman coding to the information source symbol.

The ECC circuit 300 generates an ECC code for the read data B and compares it with the read ECC code. Here, both the data memory 50 and ECC code memory 60 use SIMM which are currently put on the market.

The signal is inverted 34 and the number of high-speed clock pulses sent on a line 24 is counted by a counter 14. After the counter 12 exceeds a specific output count, the counter 14 stops and the output count indicates a selected pulse duration of an inverter drive logic signal so that the output count is read and is calculated by a circuit 18.
