What is the point of eSRAM and how do you use it?

[Björne]

I'm developing for an Agilex 7 board which is equipped with about 36 Mbit of eSRAM and 146 Mbit of M20K. Since the M20K memory is both larger and has lower access latency than the eSRAM, what is the point of using the latter? Also, is it possible to get Quartus to infer eSRAM when using Intel OpenCL or DPC++?

Hi Björne,

For eSRAM IP you can refer to this document:

https://www.intel.com/content/www/us/en/docs/programmable/683241/23-2/embedded-memory-features.html

For memory size query, I think can refer to this link:

Thanks.
