MSC8254TVT1000BHigh-performance fournucleusDSP
The MSC8254 is the industry's highest performance DSP core built on StarCore technology and advanced processing based on the needs and capabilities of today's high-performance medical imaging, aerospace, defense and advanced test and measurement markets.It offers industry-leading performance and power consumption, utilizing a highly integrated system-on-chip (SoC) on 45nm process technology to deliver a single-core device with performance equivalent to 4 GHz.The MSC8254 helps device manufacturers create end products and services that integrate more functionality in a smaller footprint.
The MSC8254 DSP offers a high level of performance and integration, combined with four fully programmable enhancements, the SC3850 DSP core, each running at up to 1 GHz.The SC3850 DSP core has been independently evaluated to make more than 40% of the processing power per MHz competitive with the closest DSP.The high-performance internal RISC-based QUICC Engine subsystem supports multiple network protocols to guarantee reliable data transmission over packet networks while significantly offloading the processing of DSP cores.
The MSC8254 embeds a large amount of internal memory to support a variety of advanced high-speed interface types, including two RapidIO® interfaces, two Gigabit Ethernet interfaces for network communications, and one PCI Express®controller, DDR controller high speed, industryStandard memory interface and four multi-channel TDM interfaces.The MSC8254 allows for a high degree of scalability and is pin-compatible with all MSC825x and MSCC815x DSP devices.
