1+n=1+2r where r=#regs when reading from HSB addresses
1+n=1+(1+r) where r=#regs when writing to HSB addresses
Requires only one cycle because write buffer was empty
Instruction filling the write buffer
Requires 2 cycles because write buffer was not empty
Next instruction has a memory access, 3 stall cycles needed
Memory not accessed in the 3 following clock cycles, no stall
Description
Instruction not using the write buffer
