CPU MODULE
General Description
The main element of the ACE3600 is the CPU module. It controls the I/O modules, processes
the gathered data and communicates with the outside world.
The core of the module is Freescale’s MPC8270 32-bit microprocessor which has extended
communication capabilities, high speed core, DMA and floating point calculation support. The
module includes on-board memory, communication ports, I/O bus interface and other circuits.
The firmware is based on Wind River’s VxWorks operating system.
Module Location: The CPU is a removable module located in a dedicated slot in the RTU rack.
The CPU module must be plugged into the wide slot to the right of the Power Supply module.
(Inserting the module in the wrong slot will not cause any damage to the CPU.)
Figure 4-1 provides a general view of the ACE3600 CPU (Models 3610 and 3640).
