Last I checked, 2 x 32 = 64. ;-)
Cool. Does that mean I can put my two old Pentium 200 MHz PCs together? :-)
Sure, go for it. ;-) Actually, years ago, you could parallel chips. Some computers, such as the Data General Eclipse, used bit slice processors. Each chip was a 4 bit ALU. So a 16 bit computer, such as the Eclipse, would use 4 of them. If you wanted a 32 bit CPU, you'd use 8. However, these weren't complete CPUs. You also had to add microcode and a fair bit of additional logic, to produce a working CPU. As I recall, the microcode for the Eclipse was over 100 bits wide. The Eclipse CPU was comprised of 2 15 inch square boards. Memory and I/O was on additional boards. Incidentally, finding bugs in the microcode was real "fun". The Eclipse had microstepping available for that, but it was still difficult.
