Part Number: AM6442

I'm searching the document which describes about benchmark result about the throughput between R5F to/from external DRAM.

Thanks and Best regards,

Tsurumoto-san,

We have some preliminary results for the STREAM Benchmark that I'm sharing below. We plan to publish these in the MCU+ SDK documentation and the AM64x Benchmarks app note soon.

Function Best Rate MB/s Avg time Min time Max time

Copy: 236.5 0.067743 0.067665 0.067803

Scale: 211.4 0.075960 0.075699 0.076119

Add: 182.9 0.131338 0.131240 0.131397

Triad: 168.8 0.142870 0.142222 0.146219

The four individual scores are copy, scale as in multiply by constant, add two numbers, and triad for multiply accumulate. For bandwidth, a byte read counts as one and a byte written counts as one.

I hope this helps.

Regards,
Sahin

Hi Sahin

Thank you so much.

So, the following number described in AM64x Benchmarks app note represent the number for A53 <--> DDR

And the number you let me know represent the number R5 <--> DDR.

Does it correct?

Thanks and Best regards,

Tsurumoto.
