The hardware resource utilizations are listed in the following table.
Table 1 : Hardware resources for ConvertCSCCSR with cache
Kernel | BRAM | URAM | DSP | FF | LUT | Frequency(MHz) |
kernel_pagerank_0 | 413 | 0 | 7 | 295330 | 207754 | 300 |
Figure 2 : Cache depth’s influence to ConvertCSCCSR acceleration
Note
1. depth 1, depth 32, depth 1k, they use LUTRAM only, in compare with resources of depth 1, only LUT and FF changes.
2. depth 4k, depth 32k, they use URAM, in compare with resources of depth 1, the URAM utilization will be the major difference.
3. HW Frequency: depth 1 (300MHz), depth 32 (300MHz), depth 1k (275.6MHz), depth 4k (300MHz), depth 32k (275.7MHz)
