RAM Access = 17.85ns(SRAM R/W) * 8bytes(64bit) = 142.85ns(CPU R/W) + 142.85ns(Video R) = 285.71ns(3.5MHz CPU Clock)aowen escribió:Turrican escribió:No. Spec256 uses a 64-bit Z80 co-processor and parallel memory to store the images. There isn't physically enough RAM or gates on the FPGA to do it.
My project Spec256 uses ROM 16K + RAM 384K (48K x 8) = 400K < 512K and 7K6 LE's < 9K LE's in FPGA
So, everything will work on ZXUno without any problems
I have another interesting two-processor project:
