Experimental Physics and
Industrial Control System

Hi,

 

Ø  However, when we are performing the same for ARM9 and

Ø  FPGA-microblaze the final slope is not coming with the data

Ø  generated though the ioc CPU is overloaded and it maintains

Ø  the plateau for ever.

Ø   

Ø  Can anybody explain the reason?

 

One important difference with an embedded processor might be that, if a hardware floating point unit isn’t available or in the case of the soft-core instantiated, then one can expect that record processing can be limited by the performance of software floating point emulation; in contrast the ca server code and the network driver don’t tend to use as much floating point as compared to the record processing. Since every ca put to a process passive field can trigger record processing then this could be a limiting factor. In that situation you might observe that you find the limit of the CPU before you find the limit imposed by the maximum throughput in the network interface.
