Freescale launched the industry's first support for 3G-LTE, WiMAX, HSPA
Freescale introduces the industry's first multi-standard accelerator that supports emerging wireless technologies such as 3G-LTE, WiMAX, HSPA + and TDD-LTE base stations
MSBA8100 device replaces expensive FPGA or custom ASIC device
June 17, 2008, Orlando, Florida (Freescale Technology Forum) --- Freescale Semiconductor has been unwaveringly promoting the development of next-generation broadband wireless base stations. It has recently launched the industry's first multi-standard baseband Accelerator device. As the first device to support 3G-LTE, the MSBA8100 also supports emerging wireless WiMAX, HSPA + and TDD-LTE standards, enabling wireless infrastructure equipment manufacturers to create extremely low-cost differential channel cards.
For operators, this advancement in silicon design has brought the deployment of LTE and other next-generation wireless networks closer to reality. The MSBA8100 multi-standard baseband accelerator supports traditional 2G / 3G technology and the latest wireless standards. Freescale is the first semiconductor company to provide customized and off-the-shelf solutions that fully meet these standards. Target applications include next-generation independent or unified 3G-LTE, WiMAX, HSPA + and TDD-LTE equipment, as well as products that support existing wireless standards.
Because there is no need to develop expensive FPGAs or custom ASIC devices, the baseband accelerator, together with Freescale's MSC8144 quad-core digital signal processor (DSP), provides flexible solutions for various base station designs. This advanced Freescale technology is designed to allow OEMs to create wireless base station equipment with data rates above 100Mbps for low-latency data packets, while at a very reasonable price to promote backbone deployment.
The combination of Freescale's MSC8144 DSP and the advanced MSBA8100 accelerator not only maintains the same flexibility as the DSP-plus-FPGA (DSP plus FPGA) solution, but also does not have the costs associated with standard product-specific adjustments. Since this solution does not require expensive dedicated components during the intermediate prototyping stage, it can also save some bill of materials costs. From the prototype method to the final system production, the same DSP-plus-baseband (DSP plus baseband) accelerator combination can be used.
"Our innovative multi-standard accelerator, together with the fully programmable MSC8144 DSP, provides wireless infrastructure device manufacturers with a low-cost scalable system," said Barry Stern, multi-core DSP manager of Freescale's Networking Systems Division.
"Through the high-performance attributes of the two devices and the ability to integrate customer-specific intellectual property rights, we provide the freedom to replace existing silicon vendors at will."
Faster time to market and cost savings. The accelerator device can effectively support the latest Turbo and Viterbi decoding standards, as well as the high-throughput FFT and DFT algorithms required by traditional and emerging 3G-LTE, WiMAX, and HSPA + standards. Compared to the solutions used in today's typical prototyping systems, this powerful and effective combination can accelerate the pace of OEM listing while significantly reducing costs.
It is also important for manufacturers of broadband wireless infrastructure to achieve cost savings while adapting to changes in emerging standards. MSBA8100 contains two configurable RISC engines, both of which can be reprogrammed in the future to accommodate updates.
"The industry is facing a strong demand for higher data rates with flexible solutions, but these solutions need to be extremely cost-effective in today's market," said Will Strauss, president of Forward Concepts, "the early 3G-LTE prototype system It has not yet reached the appropriate price point for large-scale adoption. Freescale ’s multi-standard commercial accelerators, together with fully programmable DSPs, enable a very flexible and cost-effective design. OEMs can implement converged base stations while handling 3G-HSPA and 3G- LTE. This is a great advancement that can make the leap to mass adoption. "
Suitable for unified multi-standard and scalable base stations MSBA8100 MSBA8100 allows OEMs to take full advantage of LTE and other emerging standards. The device is based on Advanced Broadband Multi-Accelerator Platform Engine (MAPLE-B) technology developed by Freescale and can accelerate Turbo and Viterbi decoding, fast Fourier transform (FFT), and inverse fast Fourier transform currently performed in FPGA or custom ASIC devices (IFFT), discrete Fourier transform (DFT) and inverse discrete Fourier transform (IDFT) operations.
Processing delay is one of the most important parameters in a broadband wireless system to reduce the round-trip time of real-time traffic. Freescale has integrated advanced high-speed interfaces into the MSBA8100 and MSC8144. This combination can be used for various system technologies with very low latency. Communication with the MSC8144 DSP and antenna is accomplished through two high-speed serial RapidIO® interfaces, each of which can be expanded to up to four 3.125Gbaud channels. MSBA8100 also includes 512 KB memory, a DDR-2 memory controller and a PCI controller.
In addition to Turbo and Virterbi decoding, MSBA8100 can also accelerate the de-rate matching of various wireless standards and security algorithms, including 3GPP EDCH, sub-block de-interlacing and de-interlacing, while providing 3G-LTE and WiMAX HARQ support.
Simplified implementation of development system In order to achieve rapid system prototyping and development, Freescale provides the MSBA8100ADS development board, which facilitates software development. The development board is shipped with the MSBA8100 device and is interconnected with the MSC8144 DSP through the on-board x4 serial RapidIO® switch to achieve true system-level design and development.
The development board also includes an AMC expansion connector to integrate with other motherboards through 4X serial RapidIO interface or ATCA cabinet and MSC8144 optimized device driver to configure and control communication with MSBA8100 device. Freescale provides a robust development tool suite for its DSP products, including the integrated development environment (IDE) in the Freescale CodeWarrior® tool suite. In addition, the reference software kernel can also assist customer development.
