Here are some good numbers for I/O. The benchmarks were completed
with an 825 and a 350. Both systems were idle. The instrument
used in the test was an hp3565 digital signal processing system.
The hp36565 is rated at 900K bytes per second.
Here goes:
825 350
Address device to talk: .004 Sec. .000168
( bytes/sec. )
100 byte transfer read: 13,063 31,565
write: 18,642 168,918
10,000 byte transfer read: 416,614 408,874
write: 453,658 409,170
65536 byte transfer read: 564,590 408,870
write: 612,497 410,158
100,000 byte transfer read: (1) 408,876
(1) 413,210
(1) The 825 locked up on transfers greater than a 16 bit short- thus,
the 65536 test? Sure hope someone plans on fixing it!!
Here is one math benchmark. The test performed a frequency response
calculation ( in polar coordinates )- The results are returned in
dBV/Deg on a 512 complex block:
825 350
.056 .077 (sec.)
DISCLAIMER
As with ALL benchmarks the above results should be taken with a grain
of salt.
