DM500HD & DM800HD & DM8000HD PROCESSOR KARŞILAŞTIRMASi
DM8000 HD
processor: 400 Mhz Mips (BCM7400) processor Flash: 128 Mbyte Ram: 256 DM800 HD processor: 300 Mhz Mips (BCM7401) processor Flash: 64 Mbyte Ram: 256 DM500 HD processor: 400 Mhz Mips (BCM7405) processor Flash: 64 Mbyte Ram: 256 General specs: DM8000 HD  DM800 HD  DM500 HD  But the real interesting is the processor chip comparaison: DM8000 HD: BCM7400 Broadcom Corporation - BCM7400 - Dual AVC/MPEG-2/VC-1 HD Digital Video Decoder For Satellite, IP And Cable The BCM7400 is a dual channel high-definition satellite, cable, and IP set-top box DVR solution offering integrated AVC(H.264/MPEG-4 Part 10), MPEG-2, MPEG-4 Part 2, DivX, and VC-1 Video decoding technology. It combines a data transport processor, two high-definition AVC/MPEG-2/VC-1 Video Decoders two advanced-audio decoders, 2D and 3D graphics processing, high-quality Video scaling and motion adaptive deinterlacing, seven Video DACs dual stereo high-fidelity Audio DACs a dual threaded 350-MHz MIPS32 with FPU class CPU, and a peripheral control unit providing a variety of set-top box control functions. The BCM7400 supports DDR2 memory architectures. The MPEG-2 DVB-compliant transport stream/PES parser and demultiplexer is capable of simultaneously processing 256 PIDs via 128 PID channels in up to six independent external transport stream inputs and four internal playback channels. All 128 PID channels CAN be used by the record, Audio and Video Interface engine (RAVE), PCR processing, message Filter and for output via the high-speed transport or remux module. The data transport module CAN be configured to support eight record channels for PVR functionality and six AV channels to Interface to Audio and Video Decoders By Broadcom Corp. DM800 HD: BCM7401 Avc/mpeg-2/vc-1 Hd Digital Video System-on-a-chip Solution For Satellite, Ip, Cable, And Watch-and-record Dvr - Broadcom Corporation. The BCM7401 is a high-definition satellite, cable, and IP set-top box DVR solution offering integrated AVC (H.264/MPEG-4 Part 10), MPEG-2, and VC-1 Video decoding technology. It combines a data transport processor, high-definition AVC/MPEG-2/VC-1 Video Decoder advanced-audio decoder, 2D graphics processing, high-quality Video scaling and motion adaptive deinterlacing, six Video DACs stereo high-fidelity Audio DACs a MIPS32/MIPS16e class CPU, and a peripheral control unit providing a variety of set-top box control functions. By Broadcom Corp. DM500 HD: BCM7405 a surprise !! Broadcom Corporation - BCM7405 - Multi-Format HD Digital Video/Audio SOC For Satellite, IP And Cable DVR STBs With Watch-and-Record DVR The BCM7405 is a high-performance, high definition (HD) satellite, cable, and IP set-top box DVR System-on-Chip solution. It combines a fast 1100-DMIPS MIPS32/MIPS16e-class CPU, high-speed graphics processing, including Video scaling and motion adaptive deinterlacing, a very flexible data transport processor, an MPEG-4/VC-1/MPEG-2/AVS-compliant Video Decoder a programmable Audio decoder, six Video DACs stereo high-fidelity Audio DACs dual Fast Ethernet ports, one with integrated PHY triple USB 2.0, a PCI 2.3/Expansion Bus, a high-speed 400-Mhz DDR2 Memory controller and a peripheral control unit that provides a variety of set-top box control functions. Integrated in 65-nm technology, it offers one of the highest levels of single-chip system performance available for STB applications. By Broadcom Corp. BCM7400 Application circuits scheme (DM8000 HD chip)  BCM7401 Application circuits scheme (DM800 HD chip)  BCM7405 Application circuits scheme (DM500 HD chip)  SONUÇ: DM8000 HD: BCM7400 = 1000 DMIPS DM800 HD: BCM7401 = 450 DMIPS DM500 HD: BCM7405 = 1100 DMIPS |
