Table 1.
Memory mapping metrics for different channel depth of the pixels (in table, N) and word length (WL).
| Memory [KB] | % Empty | # Read | # Write | ||
|---|---|---|---|---|---|
| N = 3 | IWAP | 0.288 | 0 | [1, 2] | [1, 2] |
| H = 32 | KLIP | 0.505 | 43 | 1 | 1 |
| WL = 128 | PLIP | 1.523 | 82.1 | 3 | 1 |
| N = 56 | IWAP | 1.344 | 0 | [9, 10] | [3, 4] |
| H = 8 | KLIP | 1.427 | 5.9 | 9 | [3, 4] |
| WL = 160 | PLIP | 1.436 | 6.4 | 9 | 3 |
| N = 56 | IWAP | 1.344 | 0 | 11 | 4 |
| H = 8 | KLIP | 1.4 | 4 | 11 | 4 |
| WL = 128 | PLIP | 1.528 | 12 | 12 | 4 |
For all cases, we consider 8-bit precision. Numbers in brackets indicate that different numbers can be obtained for reading or writing different pixels. N and H are the channel depth and the height of the volume of feature maps, respectively. WL is the word length of the local memory.
