-
CISC and RISC processors
-
-
-
Each CISC instruction takes multiple FDE cycles, RISC only takes one
One CISC instruction can do a simple task, RISC requires lots of instructions stacked together
GPUs
GPUs (Graphics Processing Units) rapidly manipulate and alter memory, normally used to create images to output
RAM and ROM
RAM is volatile, ROM is non-volatile
RAM is read-write, ROM is read only
-
