Table 5 Communication time between the pulse compression and Doppler filtering after optimization
Parameters | Values |
|---|---|
Number of SRIO packets to exchange between two DSP cores | 1 |
Size of each SRIO packet | Nr × 8 bytes =4 KB |
Time to send each SRIO packet using one lane (see Section 4.3.4) | 9 μs |
Communication time between two DSP cores using one SRIO lane | 9 μs |
Communication time between one DSP core and the 16 other DSP cores using one SRIO lane | 9 μs × 16 = 144 μs |
Total communication time between the two DSPs using one SRIO lane | 144 μs × 8 cores =1.15 ms |
Total communication time between the two DSPs using the four SRIO lane available | 1.15 ms / 4 = 288 μs |
