4.7. Avalon® -ST Round Robin Scheduler

Figure 139.  Avalon® -ST Round Robin SchedulerThe Avalon® -ST Round Robin Scheduler core controls the read operations from a multi-channel Avalon® -ST component that buffers data by channels. It reads the almost-full threshold values from the multiple channels in the multi-channel component and issues the read request to the Avalon® -ST source according to a round‑robin scheduling algorithm.

In a multi‑channel component, the component can store data either in the sequence that it comes in (FIFO), or in segments according to the channel. When data is stored in segments according to channels, a scheduler is needed to schedule the read operations.
