Hello,

As reference manual express:

SPE accelerates operations via the use of short vectors (two, four, or eight elements) within 64-bit
GPRs and the use of Single Instruction Multiple Data (SIMD) operations. SPE 2.1 also includes an accumulator register to allow
for certain back-to-back operations without loop unrolling.

Best regards,

Peter
