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 | 10.76 Mbps / 297.50 us | 24.18 Mbps / 132.33 us | 0.92 Mbps / 3463.92 us |
| 200 | 16 | 21.68 Mbps / 147.62 us | 30.49 Mbps / 104.97 us | 0.96 Mbps / 3339.69 us |
| 100 | 32 | 37.79 Mbps / 84.68 us | 35.45 Mbps / 90.26 us | 0.98 Mbps / 3277.71 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 |

- Calculated for the 500 samples taken between 0 and 2 * Pi
- Trignometric function timings compared between the optimized Mathlib mcusdk implementation and the compiler mathlib version
- The max error for each operation between the optimized Mathlib mcusdk functions and the compiler mathlib version is printed
