The AMD 29K had a more effective approach to this problem, with a deep register stack and a variable window. (It also had a branch target cache which sped up iteration, though with a Von Neumann architecture I don’t remember why this was a win over a unified cache). It’s a shame AMD abandoned it in its failed quest for x86 dominance. https://en.wikipedia.org/wiki/AMD_Am29000 https://en.wikipedia.org/wiki/AMD_Am29000
