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 8.61 Mbps / 371.61 us 22.20 Mbps / 144.17 us 0.91 Mbps / 3529.54 us
200 16 17.42 Mbps / 183.67 us 28.57 Mbps / 112.01 us 0.95 Mbps / 3373.64 us
100 32 31.57 Mbps / 101.36 us 33.47 Mbps / 95.60 us 0.97 Mbps / 3295.88 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
