A question of the processor

Postby Weiwei » Sun Aug 04, 2013 2:56 am

According to the datasheet each core of the processor E64G401 provides two floating point operations per clock cycle. Is that mean there are one multiplier and one adder in each core? Is there more details about the core architecture? Thanks.

I believe FMADD is counted as 2 instructions, otherwise the peak would be 800Mhz*64 = 50 GFLOPS
