Using & Implementing Differential Reference Counting in Realtime Audio Code - Palmer Hogen - ADCx SF

Safely sharing dynamic memory across threads – especially when some of those threads have strict time deadlines – is a tricky problem space; unfortunately this scenario appears in realtime audio code. Some threads may still be accessing old data, so algorithms need to carefully avoid deleting anything still in-use.

Many deferred-reclamation strategies have emerged to address this risk, but these techniques have a general tradeoff between ease-of-use and throughput; ideally we would like both!

This talk presents a variant of traditional reference counting, which offers improved throughput at the expense of a more limited API.
