Abstract
Methods and apparatuses for an optimal timer array using a single reference counter are presented. According to one aspect, timers of the timer array use the single reference counter to process different timed trigger requests. A count translation logic block translates counts corresponding to the requested timed triggers to target values of the reference counter. Register arrays that include the target values and active/inactive status flags of the timers are used to implement specific timers. Comparators are used to compare values of the reference counter to the target values to establish expiration of the requested timed triggers. A target translation logic block translates a current value of the reference counter to an offset value from the target values for monitoring by an external circuit.
Claims1
A radio frequency (RF) device, comprising:
- an RF circuit configured to process an RF signal;
- and
- a digital circuit configured to communicate with a master device separate from the RF device, the digital circuit comprising:
- a timer array configured to generate a plurality of timed triggers for synchronization of events between the master device and the RF circuit, the timer array comprising:
- a reference counter operating from a reference clock;
- and
- a count translation logic block that is configured to translate a number of reference clock counts corresponding to each timed trigger of the plurality of timed triggers to a target offset value of the reference counter.
