Thanks. How about within main memory, within a hard drive, and between an internal hard drive and an external hard drive?

comment Batch download multiple images after inspect elements in Chrome browser?
Thanks. I have tried FF + DownloadThemAll on an online book reading site, but it seems that it can't capture the pictures for the pages. Can you also try to see if it works?

comment What are functional unit and control logic of a cpu?
@slhck; about the first point, does a superscalar architecture replicate only functional units (i.e. execute unit) as said in the text, or both functional units (i.e. execute unit) and the control logic (i.e. fetch and decode units) as shown in figure 1-7(b)?

(2) Also by multithreading, the text actually means time-multiplex. Why replicating control logic is necessary for time-multiplex? Can't multiple threads share the same control units (fetch unit and decode unit) at different times?

@slhck: My questions are more than what you thought. The text says superscalar architectures replicate the functional units, while multithreading replicates not only the functional units, but also the control logic. (1) But in figure 1.7(b), the superscalar one have multiple fetch and decode units besides multiple execute units, so I am not sure if "control logic == fetch and decode units" and "functional unit == execute unit".

Thanks. do you mean that you think that functional unit and execute unit the same thing in the book? (note that I am not sure about if execute unit and execution unit are the same). what about control logic?
