The following table shows the throughput that can be achieved using a single- and dualprocessor system with the three possible FIFO sizes. The essential numbers are contained in the following table: ADC Conversions/sec without loss of data

Wolfgang, we need a clarification on the data on MPA-3 maximum rates. There are two documents with apparently conflicting and different information in them regarding the MPA-3 max rates.

1. The FAQ section on your website. A extract is shown below.

2. The 31 11 2001 "MPA-3 Performance" application note.

Which is correct?

The data in the FAQ page were obtained with a Pentium II 350 MHz processor and a dual processor board using two of these processors. The data in the application note were obtained with a Pentium III 1 GHz processor. So both are correct and show the dependence on the processor power. If the processor is fast enough, the maximum throughput does not depend on the FIFO size, but only if the full processor power is available to the MPA-3 system. You can see at the data with the single Pentium II 350 MHz, that the FIFO can enhance the throughput if less processor power is available, for example if other tasks are busy like display of large maps.
