IBM還是大幅修改Cell的SPE設計了

IBM Power Architecture Forum上的某篇文章

重點如下：

"There are already some modification going on within CELL. There is some progress in replacing the entire FPU inside the SPU with a full-blown DP (double precision) unit. The estimated performance should be about 1:2 against the current SP unit, which would be a major improvement compared to the current situation of about 1:10 - 1:14."

換句話說，如果成真，Cell的double precision FPU效能就會大幅提升至single precision的一半。

其實這一點都不讓我感到意外，Cell SPE的double precision FPU本來就該改進了。
