For starters, ARM says the the Cortex-R8 provides twice the performance of its predecessor and includes support for next generation LTE-Advanced Pro technology and 5G modems. If you recall, Qualcomm recently announced its LTE-Advanced Pro Snapdragon X16 LTE Modem, which supports wireless speeds of up to 1Gbps.
Cortex-R Series processors are mainly employed in embedding computing markets currently, with the bulk of them going into HDD and SSDs designs (ARM claims its architecture is in products from all major HDD and SSD manufacturers), modems and in the connected car movement. ARM is especially seeing growth in this last area, as advanced processors are being employed to handle self-driving routines and process data streaming from numerous cameras and sensors installed in today's cutting-edge vehicles and next generation driving systems as well. It's again these sort of applications that require fine-grained, "fast-twitch" processing, if you will, rather than heavy duty number crunching, that the new Cortex-R8 is targeted to.
ARM reports that their silicon partners have already begun design work and SoCs based on the Cortex-R8 targeting storage applications should be available sometime in 2016. Modem designs using Cortex-R8 processor architecture are also in the works and will reportedly help enable the roll-out of new LTE-Advanced Pro and 5G standards and technologies. No specific time frames for LTE-Advanced Pro and 5G designs have been disclosed at this point but manufacturers including Huawei are reportedly already working on 5G designs bolstered by the ARM Cortex-R8 architecture. A representative from Huawei, Daniel Diao, deputy general manager, Turing Processor Business Unit specifically claimed that the technology will be "widely deployed in any device where low latency and high performance communication is a critical success factor.”
