The Potential for a GPU-Like Overlay Architecture for FPGAs
Table 3
A breakdown of how each stage of an HT memory request contributes to overall access latency.
| Action | Stage | Latency (ns) |
| Request | (1) FPGA HT IP core | 70 | (2) host HT controller | 32 |
| SDRAM | (1) access and data fetch | 51 |
| | (1) host builds response packet | 12 | Response | (2) host HT controller | 30 | | (3) FPGA HT IP core | 110 |
| | Total Latency | 305 |
