RISC
RISC (reduced instruction set computers) . .
A RISC processor has 8 global registers and 10 register windows. Each window has 4 parameters registers, 8 local registers, and 4 temporary registers. How many total registers are in this CPU?

P.S. Amd 29000 intel 960 - ( i960 ), , .The SPARC processor usually contains as many as 128 general purpose registers. At any point, only 32 of them are immediately visible to software - 8 are global registers (one of which, g0, is hard-wired to zero, so only 7 of them are usable as registers) and the other 24 are from the stack of registers. These 24 registers form what is called a register window, and at function call/return, this window is moved up and down the register stack. Each window has 8 local registers and shares 8 registers with each of the adjacent windows.
