Result Interpretation

Peripheral DMA Channel Arbitration Delay Calculator computes Arbitration Delay in s using the defined engineering formula and the input values provided. Arbitration Delay is expressed in s. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • Number of Concurrent DMA Channels = 2
  • Bus Clock Period = 2.0E-9
  • Maximum Arbitration Cycles per Request = 2

Expected Result:

  • Arbitration Delay = 4.0E-9

Engineering Interpretation:

Under the given input conditions, the calculated result is: Arbitration Delay = 4.0E-9 s.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.

Formula / Method

arbitration delay = (number of concurrent dma channels - 1) * bus clock period * maximum arbitration cycles per request

Frequently Asked Questions

What does this calculator calculate?

The Peripheral DMA Channel Arbitration Delay Calculator estimates Arbitration Delay based on the input parameters you provide

Why is bus clock period important in this calculation?

bus clock period is directly proportional to arbitration delay. When you enter bus clock period in s, the calculator uses it in the engineering formula to compute the output

How should I interpret the result arbitration delay?

The calculator outputs arbitration delay in s. The result is computed directly from the input values using the defined engineering formula

What units should I use for the inputs?

Enter each value in the units shown next to the input field: Bus Clock Period (s). Make sure all inputs use the specified units for consistent results

What assumptions does this calculator use?

This calculator uses automatically validated engineering formulas. Results are approximate and should be validated against site-specific conditions, applicable codes, and professional engineering judgment
