It is very clear from related descriptions of the F21 CPU(a related design http://www.ultratechnology.com/f21cpu.html http://www.ultratechnology.com/f21cpu.html) that the intention behind the design is to reduce the bandwidth requirements for fetching data instructions thus the rather convoluted claim that the CPU runs at four times the speed of memory because it can fetch four five bit instructions from a single memory word access. This really doesn't make sense and when combined with sentences like "Increasing speed in the RISC processor creates a large disparity between the processor and the slower memory. To increase the memory accessing speed, it is necessary to use cache memory to buffer instruction and data streams. The cache memory brings in a whole set of problems which complicate the system design and render the system more expensive." I'm really quite at a loss. The claim is that the processor is faster because it is simpler so it has a higher instructions per clock and can avoid a high clock disparity between CPU and ram. Well, if your processor is faster it doesn't matter if it comes from IPC or faster clock; memory will still be slow so this design philosophy simply doesn't make sense to me.
