1.2.2.1. Comparison between Serial Flash Mailbox, Mailbox Client and Mailbox Client with Avalon® Streaming Interface IPs

The following table summarizes the comparison between each of the IPs.

  Mailbox Client with Avalon® Streaming Interface IP Serial Flash Mailbox Client IP Mailbox Client IP
Supported Devices Agilex™ 7 devices only Stratix® 10 devices only
  • Agilex™ FPGA portfolio
  • Stratix® 10 devices
Interfaces Avalon® streaming interface Avalon® memory-mapped interface Avalon® memory-mapped interface
Recommendations Host controller which uses Avalon® streaming interface to stream data. Host controller which uses Avalon® memory-mapped interface to perform read and write.
  • Host controller which uses Avalon® memory-mapped interface to perform read and write.
  • Recommended to use this IP in Stratix® 10 devices.
  • Easy to migrate from Stratix® 10 devices to Agilex™ 7 devices.
Data Transfer Speed Faster data streaming than Serial Flash Mailbox Client IP and Mailbox Client IP. Slower data streaming than Mailbox Client with Avalon® Streaming Interface IP. Slower data streaming than Mailbox Client with Avalon® Streaming Interface IP.
