Numerical value, the correct count value of decoding.
Specific character count value is obtained using specific character statistical counter, to the specific character in data flow
(this specific character may come from the configuration of software view) is counted, every in decision-feedback module 403
The secondary character boundary that sends adjusts statistical result clearing after control signal, for a parallel character or multiple character
In, as long as there being a correct specific character, then this specific character statistical counter adds one, and carries out addition
Overflow protection.
Using the correct number of continuous decoding in continuous decoding correct statistical counter statistical decoder data flow, should
Enumerator often runs into one or more decoding errors in parallel data stream and then resets, and otherwise from Jia one, works as counting
During to continuously correct thresholding, then reset, this continuously correct thresholding can be arranged by software.
Decoding error count value is obtained using decoding error statistical counter, this statistical counter often runs into simultaneously
In row data flow during one or more decoding error, then certainly Jia one, when correct statistical counter of continuous decoding etc.
When continuously correct thresholding, this enumerator, from subtracting one, plus one and is subtracted and do overflow protection for the moment.Feedback judging module
When state machine within 403 redirects, this counter O reset.
To obtain the correct count value of decoding using decoding correct statistical counter, this statistical counter often runs into simultaneously
In row data flow during one or more decoding error, then certainly subtract one, when correct statistical counter of continuous decoding etc.
When continuously correct thresholding, from Jia one, plus one and subtract a period of time does overflow protection to this enumerator.Feedback judging module
When state machine within 403 redirects, this counter O reset.
United using the time that intervalometer is in each state to the state machine within feedback judging module 403
Meter, when state machine redirects, automatic clear, otherwise certainly Jia one, and carry out overflow protection.
Feedback judging module 403 is internally provided with a state machine, shown in Figure 5, totally three states：
Boundary adjustment state, synchronization judge state, synchronous regime.
Boundary adjustment state：I.e. original state, in the action of this state execution character boundary adjustment.This state
Unconditional jump judges state to synchronous.
Judge state synchronous：When the count value of decoding error statistical counter exceedes the mistake meter of software arrangements
Number thresholdings or timer count value exceed the timer threshold of software design patterns then it is assumed that current character boundary adjustment
Mistake, at this moment state machine jump to boundary adjustment state.
When the count value of specific character statistical counter exceedes the specific character thresholding of software design patterns and decodes correct
When the count value of statistical counter exceedes the correct count threshold of software design patterns, then jump to synchronous regime, table
Show that current character boundary is correct.
Continue decoding error statistical counter is monitored in synchronous regime, when the count value of this enumerator surpasses
Cross software design patterns error count thresholding when, then jump to boundary adjustment state, represent that mistake excessively leads to lose
Step.
Export a boundary adjustment control signal in boundary adjustment state to character boundary adjusting module 404.
