New Processor Core to Improve Performance and Efficiency for LTE and 5G


May 23, 2018

According to a recent release, MIPS, processor architecture and IP core for licensing company, has made available its new I7200 multi-threaded multi-core processor, which is a new high performance licensable IP core in the 32-bit range. The I7200 reportedly delivers 50 percent higher performance with less than 20 percent area increase over the previous generation.

“MIPS CPUs are widely used in a range of LTE applications for mobile broadband,” said David Lau, VP, Engineering, MIPS. “The performance gains across the board on the new I7200 deliver a leap forward in support of the transition to 5G systems, while providing a range of configurable features that enable the CPU core to be optimized for a specific application. For communications processing in LTE modems, where small size and power consumption are at a premium, and latency and deterministic responsiveness are critical to system performance, the I7200 can be tuned to optimize the characteristics for real-time embedded processing.”

Part of the MIPS 32-bit I-Class family of processor cores, the I7200 is built on MIPS’ multi-threading technology, which delivers not only these higher levels of performance efficiently, but is a key mechanism supporting very low latency response to high priority events in real-time embedded systems. Some key attributes are:

  • Simultaneous multi-threading with thread prioritization and zero cycle context switching
  •  Configurable memory management – options for full TLB-based MMU or simpler, deterministic 32 region memory protection unit (MPU)
  • Tightly coupled, fast-access, deterministic ScratchPad RAMs (SPRAMs, up to 1 MB each) for instructions, data for each core, or unified implementations

“MIPS CPUs, with their powerful multi-threading capability, offer a combination of efficiency and high throughput for LTE modems that contributes significantly to system performance,” said Dr. Kevin Jou, SVP and CTO, MediaTek. “The development of the I7200 was a worldwide effort led by the MIPS Shanghai design team, and the processor promises to provide key advantages for LTE Advanced/5G features including higher computing performance and faster real-time responsiveness where multiple latency-sensitive tasks are handled simultaneously.”
