Abstract
High speed synchronous counters are constrained to operate within certain speeds due to delays inherent in the counter configurations. By utilizing look-ahead carries, that is, producing carry signals in anticipation of when they might be required, much of the delay can be eliminated. Speed performance can be further improved by fashioning the look-ahead carry system from programmable gate arrays, where non-standard logic structures can be created.
