MSC8122TMP4800V EQuad-core16 bitsDSPandEthernet
MSC8122 is a heightintegrationThe system's single-chip combination combines four StarCore SC140 expansion cores with RS-232 serial interfaces, four time division multiplexing (TDM) serial interfaces, 32 general-purpose timers, and a flexible systemInterface Unit (SIU), an Ethernet interface, and a multi-channel DMA controller.Four extended cores provide full DSP MMACS performance at 4800/6400/8000 300/400/500 MHz.
Each core has 4 arithmetic logic units (ALUs), internal memory, a write buffer, and two interrupt controllers.The MSC8122 is optimized for applications targeting high-bandwidth computing DSPs and wireless transcoding and packet telephony, as well as high-bandwidth base station applications.The MSC8122 provides enhanced performance while maintaining low power consumption, significantly reducing system cost.
The MSC8122 device is designed to provide an optimal solution for 3G wireless base stations to help eliminate many expensive and power-hungry ASICs and FPGAs in today's systems requiring both symbol rate and chip rate assistance.In addition, the MSC8122 device allows customers to add next-generation functionality to efficiently utilize the available frequencies and bit rates higher in 3G systems.
Efficient application software development is key to Freescale's strategy to accelerate customer time to market.Developers can take advantage of development tools and real-time operating systems (RTOS) from Freescale and third-party vendors.In addition, Freescale is working with third-party vendors to provide integrated system solutions, including GSM, CDMA, TDMA, and ITU G.7XX voice encoders, hybrid echo cancellation, fax, modems and xDSL software.
