Controlling an accumulation of timing errors in a synchronous system

Abstract

Apparatus () for communicating clock correction data between two or more clocked entities () using a standardized clock correction unit or quanta. A source-native pre-scaler () can convert source-native clock correction values to scaled source-native clock correction values. The pre-scaler can perform this conversion by multiplying each source-native clock correction value by a factor N. A source-native divider () can divide an adjusted source-native clock correction value by a value Mto produce a standard quotient and a standard remainder. The standard quotient defines a standard clock correction value. Further, a source-native accumulatorcan accumulate a sum comprised of the scaled source-native clock corrections and the standard remainder produced from the source-native divider. The sum can define the adjusted source-native clock correction value.
