MSC8122MP8000 E Quad-core 16-bit DSP with Ethernet
MSC8122 is a single-chip for a highly integrated system that combines four StarCore SC140 expansion cores with RS-232 serial interfaces, four time-division multiplexing (TDM) serial interfaces, 32 universal timers, a flexible system interface unit (SIU), an Ethernet interface, and a multi-channel DMA controller. Four expanded cores can deliver comprehensive 4800/6400/8000 300/400/500 MHz DSP MMACS performance. Each core has 4 arithmetic logic units (ALUs), internal memory, a write buffer, and two interrupt controllers. MSC8122 optimized for applications targeting high-bandwidth compute DSPs and wireless transcoding and packet phones and high-bandwidth base station applications. MSC8122 provides enhanced performance while maintaining low power consumption, significantly reducing system costs. MSC8122 device design provides an optimal solution for 3G wireless base stations to help eliminate many expensive and power-hungry ASICs and FPGAs that require both symbol rate and chip rate assistance in today's systems. In addition, MSC8122 devices allow customers to add next-generation capabilities to efficiently utilize the higher frequencies and bitrates available 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) provided by Freescale and third-party vendors. In addition, Freescale is working with third-party vendors to provide integrated system solutions, including voice encoders, hybrid echo cancellation, fax, modems, and xDSL software for GSM, CDMA, TDMA, and ITU G.7XX.
