“ One very fast central processor would be preferable. I don\'t think all programmers have the ability to program two CPUs — most can only get about one-and-a-half times the speed you can get from one SH-2. I think that only one in 100 programmers are good enough to get this kind of speed [nearly double] out of the Saturn. ”
—Yu Suzuki reflecting upon Saturn Virtua Fighter development
The implementation of dual CPUs within Saturn was not ideal. The biggest disadvantage of the architecture was that both processors shared the same bus and had problems accessing the main system RAM at the same time. The 4 KiB of cache memory in each CPU was critical to maintaining performance. In general, very careful division of processing, in addition to the already-challenging task of parallelizing the code, was required to get the most out of the Saturn. One example of how the Saturn was utilized was with Virtua Fighter\'s use of one CPU for each character.
Wiki上经常可以找到一些有趣的秘史,比如N64其实只用到32位性能之类的
