MCSPI performance
MCSPI driver performance in different modes
- measurement is provided for Master mode in Loopback configuration with TX and RX.
- Transfer time captured with driver API in different operation mode.
- Throughput comparison is added for transfer of 400 Bytes with different word width and corresponding number of words.
- Time
- CPU : R5F
- Transfer Length : 400 Bytes
- SPI Clock speed : 50MHz
| Number of Words | Word Width (Bits) | Polled mode Throughput / Transfer time | Interrupt mode (Mbps) Throughput / Transfer time | Dma mode (Mbps) Throughput / Transfer time |
| 400 | 08 | 8.62 Mbps / 371.33 us | 22.17 Mbps / 144.37 us | 0.92 Mbps / 3475.20 us |
| 200 | 16 | 17.44 Mbps / 183.44 us | 28.65 Mbps / 111.68 us | 0.96 Mbps / 3346.91 us |
| 100 | 32 | 31.65 Mbps / 101.10 us | 33.68 Mbps / 95.00 us | 0.97 Mbps / 3282.92 us |
- Theoretically for 400 Bytes at 50MHz time required for clocks is 64us.
- Additionally hardware adds 160ns + 1bit time delay between each word transfer as measured in the scope
DPL Low latency interrupt performance
| Interrupt handler | Measured execution time (ns) |
| Non Re-entrant, Without FPU context save | 310 |
| Non Re-entrant, With FPU context save | 426 |
| Re-entrant, Without FPU context save | 376 |
| Re-entrant, With FPU context save | 496 |
