Examples
Try the starting example
- DMA blocks [channel ID,bytes,priority (smaller first)]
- [[1,1000,0],[2,2000,1],[1,500,0]]
- Shared bus throughput (bytes/s)
- 1000000
- Per-block setup overhead (seconds)
- 1e-05
- Nonpreemptive transfer schedule
- [[0,0,0.00101],[2,0.00101,0.00152],[1,0.00152,0.00353]]
- Total completion time (seconds)
- 0.00353
Try another scenario
- DMA blocks [channel ID,bytes,priority (smaller first)]
- [[1,1000,0],[2,2000,1],[1,500,0]]
- Shared bus throughput (bytes/s)
- 500000
- Per-block setup overhead (seconds)
- 1e-05
- Nonpreemptive transfer schedule
- [[0,0,0.00201],[2,0.00201,0.00302],[1,0.00302,0.00703]]
- Total completion time (seconds)
- 0.00703
Calculation method
Calculation method
Nonpreemptive transfer schedule
All blocks ready at t=0; stable priority order then original input order; [row,start,end].
Total completion time (seconds)
Sum setup and transfer durations on one shared bus.
Symbols and units
- a
- DMA blocks [channel ID,bytes,priority (smaller first)]
- b
- Shared bus throughput (bytes/s)
- c
- Per-block setup overhead (seconds)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Single shared nonpreemptive DMA bus, all supplied blocks ready at time zero. This is a declared scheduling model, not a hardware DMA simulator. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Shared bus throughput (bytes/s): minimum 1e-12, maximum 1000000000000.0. Per-block setup overhead (seconds): minimum 0, maximum 1000000000000.0.
