The 68000 can be used for simple programs just as an 8-bit chip can. But if you have a complicated data structure or routine to program, the 68000 will make your life easier because it provides you with more tools for implementing such things. An 8-bit chip makes you do all the work with long sequences of simple instructions: the 68000 lets you use just a few, more powerful instructions. Many functions that took planning and programming on an 8-bit chip are reduced to a single, automatic operation on the 68000. This process appears in many technologies and is particularly strong in microelec- tronics. While the chips become more powerful, us- ing them doesn't get more difficult (which is nice because we aren't getting smarter). The elemental functions of the chips just keep advancing. Multiply- ing I6-bit numbers or setting up a portion of the stack for a subroutine was a major programming task on a 4-bit microprocessor and required a
