checksum

Definitions

  • WordNet 3.6
    • n checksum a digit representing the sum of the digits in an instance of digital data; used to check whether errors have occurred in transmission or storage
    • ***

Usage


In science:

To reduce the size of the result-log, we utilize a technique called CheckSum, which can signi´Čücantly reduce the amount of data with lossy compression.
RepTFD: Replay Based Transient Fault Detection
As shown in Algorithm 1, RepTFD employs a 32-bit checksum register and a few gates for each core to summarize the instruction results on the core.
RepTFD: Replay Based Transient Fault Detection
The value of each checksum register is initialized to 0 at reset.
RepTFD: Replay Based Transient Fault Detection
When committing an instruction, the new value of the checksum register is changed to the the result of the instruction XOR the old value of the checksum register.
RepTFD: Replay Based Transient Fault Detection
Obviously, the size of the CheckSum result-log is quite small: it only consumes 4 byte per kilo instructions.
