Embodiment 1

[0047] Please refer to Fig. 4, which is a flow chart of decoding 16-bit one-hot codes into 8421 codes in Embodiment 1 of the present invention, which mainly includes steps:

[0048] Step S40, determine the codeword length L of the 8421 code corresponding to the 16-bit one-hot code b , due to L b =cell(log 2 (L o )), where cell(X) means to take the smallest integer greater than X, L o is the codeword length of one-hot code, so the codeword length of 8421 code corresponding to 16-bit one-hot code is equal to 5.

Abstract

The invention discloses a decoding method to decode one-bit heat code into binary code and one-bit heat code decoder, which comprises the following parts: building the binary code matrix corresponding to the one-bit heat code; making the input one-bit heat code and each row of matrix do 'and' operation respectively; or making '1' position of each row in the matrix and the vector extracted from one-bit heat code do 'or' operation; obtaining the binary code sequence corresponding to one-bit heat code according to split condition. The one-bit heat code decoder consists of logic calculating mode and ordering mode. The invention simplifies the structure of one-bit heat code decoder, which reduces the cost with high decoding speed.

Description

technical field [0001] The invention relates to a decoding technology, in particular to a method for decoding a one-hot code into a binary code and a one-hot code decoder. Background technique [0002] In the design of modern digital logic circuits, one-hot encoding method is a common encoding method. It is characterized in that for any given state, at most one state bit is "1" and all other state bits are "0". For example, use "0001" to represent "1", "0010" to represent "2"..."1000" to represent "4" and so on. [0003] The advantages of adopting one-hot code encoding method are: easy to synthesize, easy to find critical paths, and easy to perform static timing analysis. Specifically, to determine whether it is currently in a certain state, it only needs to determine whether the corresponding state bit is "1" or "0". Considering a typical output, it outputs 1 in some specific states, and outputs 0 in the rest of the states, you only need to "OR" the state bits correspond...
