Powerful hardware for efficient high-speed processing

The AC 800PEC combines the floating-point computing

performance of the CPU with the flexibility and high speed

capability of an FPGA.

The system is separated into three performance levels

covering different cycle times. Control tasks are allocated

depending on their speed requirements:

− Very fast tasks down to 25 ns

− Fast tasks down to 100 μs

− Slow tasks down to 1 ms

The hardware architecture of the AC 800PEC is an ideal

match to the three-level software structure.

To support the short processing cycle times, the AC 800PEC

provides a fast I/O system. Depending on the speed of the I/O

connection, it is possible to achieve data throughput times

below 100 μs – including the time required to read, transmit,

process, transmit and write the signal.
