Title: Automatic generating method for decoding table of variable length code
Inventor: ARAKI SADAFUMI
IPC: H04N1/41
Filed: 1990-01-26
Abstract: PURPOSE:To automatically generate a decoding table for efficiently decoding a variable length code to one memory by generating the decoding table as to other intermediate and its succeeding nodes from an address succeeding to a termination address to be stored when the decoding table is recursively generated by using the intermediate node as a new root node as to the intermediate node connecting to a root node of a code tree appearing after the intermediate node whose coded table is generated. CONSTITUTION:A decoding consecutive instruction of 'fetch 2-bit and jump to address 1' is written to a head address 'address' = 0 on a decoded table. Then a bit number resulting from subtracting a minimum code bit number = 2-bit from each code bit number respectively is used as a new code bit number and a 'weight' of each termination node is newly calculated in response to the code bit number. Then let 'stp' = 0 be set and the sum of 'weight' of each termination node is calculated in the order of the value of 'point' and the 'point' when the sum reaches '1' at first is used as 'enp'. When the above processing operation is repeated recursively till the intermediate node is lost, the decoded table is finally generated.
