Dr. Dobb 的 Larrabee ISA 介绍文章:

其中提到:
"in the initial version of the hardware, a few aspects of the Larrabee architecture -- in particular vcompress, vexpand, vgather, vscatter, and transcendentals and other higher math functions -- are implemented as pseudo-instructions, using hardware-assisted instruction sequences, although this will change in the future. "
总之比单纯看那两个幻灯片有意义的多。 |
