MSC8144EVT800AQuad-coreDSP
MSC8144processorIt is the third generation of Freescale's high-performance multicore DSP devices, wired and wireless infrastructure applications.It is built on the successful previous multi-core DSP design to enhance the rapidly expanding voice/video/data triple playback services in this area.This multi-core DSP offers the industry's highest level of performance and integration, combined with four fully programmable StarCore DSP cores, each running at up to 1 GHz in a highly optimized architecture for voice, fax, video, and data compression processing.
The packet processor inside the QUICC engine of dual RISC supports multiple network protocols to ensure reliable data transmission over the packet network, while significantly offloading such processing to the DSP core.
The MSC8144 embeds the industry's largest internal memory and supports a variety of advanced interface types, including high-speed Ethernet and UTOPIA network communications, DDR controller high-speed, industry-standard memory interfaces, and multi-channel TDM interfaces for connecting toPSTN networking and serial RapidIO® and PCI interfaces are used to connect to other devices mounted in the same rack or board.
As a highly flexible, fully programmable, and powerful multimedia DSP, the MSC8144 delivers powerful processing power while maintaining a competitive price and power consumption per channel.
