New issue 2320: PowerPC VSX support https://bitbucket.org/pypy/pypy/issues/2320/powerpc-vsx-support
Richard Plangger: The goal is to enhance the backend to support PowerPC SIMD unit. Ultimately this will enhance the execution speed of micro NumPy. Only the most recent ISA will be supported. A hard requirement for the time being is the support for unaligned loads/stores. What to expect: As soon as enough time is spent in the optimized (vectorized) code, one can measure faster execution. For a micro benchmark stressing the implementation it would be a factor of 1.5x-2.0x speedup for e.g. float (64bit) addition/multiplication. A benchmark run will evaluate the implementation on ppc and compare it to x86.
