TRANSCODER PLATFORM MEDIA GATEWAYS
SG2125/D, 12/2002
OVERVIEW
Freescale Semiconductor, Inc.
Data networks telecommunications converging toward Internet protocol (IP) telephony infrastructure carrying voice, video, data. wireless telecommunications, trend largely same, with third generation wireless infrastructure pacing towards IP-based core network differentiated only radio interface mobility access. Since voice transcoder solutions usually implemented bank many digital signal processors (DSP), common thread through these network applications need competitive, programmable solutions, where selection criterion user channel capacity versus power consumption, footprint, course, cost.
BENEFITS
Provides high performance meet demanding requirements simultaneously processing multiple communications channels Provides power consumption meet system budget Provides integrated network connectivity

MOTOROLA ORDERING INFORMATION
Part Number XC8101M1375C Product Highlights 332-pin FC-BGA package; MHz; 1375 MMACS; CPM; system bus; EFCOP Additional Information core, I/O; 512K-byte unified program data memory configured application, ALUs, EFCOP, CPM, system integration unit. 16-channel DMA, 64-bit 60x-compatible system bus. Suitable networking infrastructure applications such 2.5G wireless infrastructure, telephony (voice, fax, modem, video gateways). Aedge/carrier switching transmissions centralized services (compression echo cancellation).
DESIGN CHALLENGES
telephony network element media gateway, where voice data standards translated from network standard another, case voice, compression standard another. Voice compression standards like ITU-defined G.729a G.723.1 convey voice that then wrapped within IP/UDP frame over network. However, this have exchanged with G.711 coded voice delivery over public switched telephone network (PSTN). Because single voice/data/video standard available, some exchange translation always needed, least network transitions into another. realize translation, real time filter bias CODECs best implemented programmable, fixed-point DSPs. Using voice transcoding example, each card telephony media gateway rack typically bound power budget supplied from backplane, engineering objective maximum number voice channels this power budget. voice transcoding card only type card within gateway equipment. Other cards control network communication cards packet and/or PTSN links. Typically, cards plug into common backplane communicate data control flows with each other.

MOTOROLA SOLUTION
Figure illustrates CODEC reference platform reference card gateway system. Although dominated concentrated processing capability, reference card also deals with data from selected backplane. Within equipment, this typically means data from Aswitch backplane. Within telephony gateways backplane could typically ATM, Ethernet, H110. CODEC platform lays down hardware processing performance 256-channel AMR/EFR voice transcode support within 14-watt power budget, based general gateway architecture (Figure Even though more than half power budget allocated backplane off-board communications, CODEC system still demonstrates very competitive channel density. MCS8101 true "network-ready" DSP. communications processor with multiple programmable, high-speed serial channels accommodates multiple physical communication links demanded both off-board within card. These include ATM, AAL2, 100Base-T Ethernet packet-based links traditional time-division multiplexed (TDM) interconnects. Together with SC140 core's control code capability, MSC8101 equally capable control managing system dealing with network protocol stack bank device running critical real-time media CODEC. used both functions CODEC board.

processing responsibility partitioned that backplane MSC8101 StarCore®-based handles off-board packet communications while tightly coupled control manages controls multi-channels allocated main bank DSPs. bank DSPs real media conversion workhorses, taking compressed speech data decompressing with software programmable CODEC like Adaptive MultiRate (AMR) G.729a voice coders. competitive SC140 StarCore architecture delivers channels device across dedicated MSC8101 devices total channels. CODEC platform both powerful flexible nature. pure voice transcode system does require external memory because full channel count supported internally within MSC8101's 512K-byte onboard memory. However, telephony universal port solution, shared external SDRAM gives added memory support voice, fax, particular, modem channels. single shared memory across four DSPs minimizes added system cost. Using general purpose SC140 core with leading performance power means channel performance quickly re-targeted CODEC technologies software optimizations become available future.
