2 Overview/Description
The GreenFIELD System-On-Chip is a low-cost,
versatile high performance and reconfigurable micro-
controller able to manage control tasks within
complex Telecommunication Infrastructure equipment
such as Base Transceiver Stations.
The GreenFIELD ASSP is designed to be extremely
flexible and it can be used in many places
within Telecom Equipment. It can fulfill control
tasks as well as monitoring. Figure 1 shows a
block diagram of the GreenFIELD.
The Embedded FPGA technology offers a high degree
of flexibility. It allows the GreenFIELD to be
reconfigured. The Embedded FPGA can be used to
remap I/Os or to implement specific custom logic.
