Epiphany memory location

[Jimmy_G]

Hey, I have read the architectural reference and the parallella reference manual, and it is still unclear to me if the Epiphany cores 32 KB local memory is physically located by each core or if they use a dedicated location on the 1GB RAM. In the later case, what is the cost for the ARM accessing them?

Yes, the 32KB is local to each core. Access time is single cycle.

The Epiphany can also access the DRAM, but then the access time is >100 clock cycles.
