The X-GOLD® SDR 2x family of programmable baseband processors is designed for hosting multiple standards of mobile communication, connectivity, and reception of broadcast services. Processors from the X-GOLD® SDR 2x family obtain the necessary flexibility from a set of programmable SIMD (single-instruction, multiple-data) processor cores, which exchange data through shared on-chip memories. The processors are supported by few dedicated configurable hardware accelerators for those DSP tasks which require no or little flexibility, by an ARM® core for the execution of the upper layers of the protocol stack and by standard IO-components.
