Since the PA6T-1682M has yet to tape out, there are no hard performance numbers. However, P.A. Semi does have performance estimates based on extensive simulations. The results certainly look promising, with per core SPECint_2k estimated at 1100 and SPECFP_2k at 2255. In terms of more application specific performance, the whole chip can handle 10Gbps IPSec and SSL encryption, or 3,000 public key handshakes per second (using software). As a RAID 5 controller, it can sustain 2GB/s, which is enough to saturate around 26 hard drives. These numbers are extremely good for a chip that only dissipates around 13W, particularly the SPECFP_2k numbers. Unfortunately, since I am not a specialist in embedded systems, it is a bit hard for me to put these numbers in context. My overall assessment is that compared to other embedded systems, the PA6T-1682M will probably have superior performance, better compute density, extra features and certainly more flexible I/O.
PRAM,如果你这是在写论文的时候玩这手,你的学术生命就到头了。我已经说过,cheery pick是极其严重的问题,足以让一个大牌教授名誉扫地。 |
