The name "vector" is actually just a special case of a one-dimensional matrix. Actually, some people use the term as a verb: "the processor vectors to...". a vector of instructions (that may be abused [sic] to store part of the program if that interrupt source isn't needed) Actually, I think the spacing of the vectors in the 8051 is specifically designed so that you can fit the (start of) the handler into the vector table entry. It's just a question of view. Some people consider both the above as interrupt vector tables. Some people consider only the table of addresses to be interrupt vector tables. I guess most people's view is coloured by whichever type they encountered first. You'll be able to guess which one I started with... But the naming is irrelevant. True - but unfortunate that the same name is used for such different things! The important thing here is to notice the huge difference in behaviour between a processor that loads an address from a vector element, and a processor to jumps to the vector elements and expects to find instructions there. Indeed - never assume that, just because architecture 'A' does a thing one way, any other architecture will do it the same way! |
