Yes, you can call it scratchpad or sram. The point is that there is no hardware caching. The local SRAM is split into 4 separate banks so it is "effectively" 4

Yes, you can call it scratchpad or sram. The point is that there is no hardware caching. The local SRAM is split into 4 separate banks so it is "effectively" 4 ported. DRAM controllers is up to the system designer. This is handled by the FPGA. (like previous epiphany chips).
