In an all-digital phase-locked loop (ADPLL), time-to-digital converter (TDC) is a paramount block. Nevertheless, design issues and solutions to resolve them always increase the complexity of the system. A novel strategy to handle the frequency error detection in a type-II ADPLL ...
A side benefit is often the capability for limited error detection. A channel coder precedes the line coder as shown in figure 11–1, and is designed specifically for one of three purposes: Error detectioncan be used to increase reliability. For example, a code can be devised that will ...

However, the implementation only demonstrates correction of the flow rate printing parameter and only in one geometry that is used for both training and testing the system. There is also a significant delay between error detection and correction. As is the case with error detection, the ...
Parity codes provide perhaps the simplest form of fault detection. An even parity code needs one check bit that is the XOR of all the data bits. Parity codes can detect single-bit faults and faults in odd numbers of data bits. SEC codes add a set of check bits to correct single-bit ...
So the error detection capability of a code is dmin−1, and the error correction capability of a code is ⌊dmin/2⌋, where ⌊⋅⌋ is the least integer function. This last is so because if fewer than ⌊dmin/2⌋ errors occur, the received string is still closer (in Hamming...
Methods, devices, and systems for determining location of error detection data are described. One method for operating a memory unit having a bad group of memory cells includes determining a location
error detection and correction at the minimum penalty of one clock cycle delay at the normal circuit operation for each error correction. No extra memory elements are required, like in earlier design approaches in the open literature, reducing drastically the silicon area overhead, while the ...
