Table 104. NVDS Read Time (Continued)
If NVDS read performance is critical to your software architecture, there are some things
you can do to optimize your code for speed, listed in order from most helpful to least
helpful:
Operation
Read (128 byte array)
Write (16 byte array)
Write (64 byte array)
Write (128 byte array)
Illegal Read
Illegal Write
•
•
Periodically refresh all addresses that are used. The optimal use of NVDS in terms of
speed is to rotate the writes evenly among all addresses planned to use, bringing all
reads closer to the minimum read time. Because the minimum read time is much less
than the write time, however, actual speed benefits are not always realized.
Use as few unique addresses as possible: this helps to optimize the impact of
refreshing as well as minimize the requirement for it.
