Hi, I have some C64 code that I'd like to port to an ARM A9 with the neon SIMD extensions. In general, are there corollaries to the intrinsic instructions used in the C64 for the A9 with neon? I'm concerend that if I port an application between the two that the number of clock cycles to perform a task will go up. Going down is good, but up is bad. Is there any kind of a rule of thumb? Are they 1 to 1?
