Introducing MIPS I7200 Processor Core<br />

MIPS, provider of the widely<br />

used MIPS processor architecture<br />

and IP cores for licensing,<br />

announced the I7200 multithreaded<br />

multi-core processor, a<br />

new high performance licensable<br />

IP core in their midrange 32-bit<br />

product lineup. Class-leading<br />

efficiency is essential to power<br />

sensitive applications such as the<br />

high bandwidth modem subsystems<br />

in Advanced LTE Pro and<br />

upcoming 5G smartphone SoCs,<br />

as well as networking ICs, and<br />

other applications. The I7200<br />

delivers 50% higher performance<br />

in less than 20% area increase<br />

than the previous generation<br />

from MIPS.<br />

Part of the MIPS 32-bit I-Class<br />

family of processor cores, the<br />

I7200 is built on MIPS’ multithreading<br />

technology, which<br />

delivers not only these higher<br />

levels of performance efficiently,<br />

but is a key mechanism supporting<br />

very low latency response<br />

to high priority events in realtime<br />

embedded systems. These<br />

characteristics, in combination<br />

with the following deterministic<br />

features available in the I7200,<br />

make it the ideal processor for<br />

embedded applications requiring<br />

both high performance and fast<br />

response to real-time events:<br />

• Simultaneous multi-threading<br />

with thread prioritization and<br />

zero cycle context switching<br />

• Configurable memory management<br />

– options for full TLBbased<br />

MMU or simpler, deterministic<br />

32 region memory<br />

protection unit (MPU)<br />

• Tightly coupled, fast-access,<br />

deterministic ScratchPad<br />

RAMs (SPRAMs, up to 1 MB<br />

each) for instructions, data for<br />

each core, or unified implementations<br />

Complementing the focus for use<br />

in embedded real-time systems,<br />

the I7200 is the first MIPS core<br />

to use the nanoMIPS ISA, which<br />

delivers industry-leading small<br />

code size. nanoMIPS is a variable<br />

instruction length ISA consisting<br />

of 16/32/48-bit instructions<br />

and numerous other optimizations<br />

that complement goals<br />

of delivering performance in<br />

smallest code size. Using an<br />

equivalent compiler and compile<br />

flags the code size is up to 10%<br />

smaller than alternative cores<br />

competing in similar applications.<br />

This reduces the overall<br />

memory footprint for a system,<br />

but is essential for high performance<br />

communications and<br />

real-time embedded systems,<br />

as it maximizes the amount<br />

of code that can be fit into the<br />

fastest, local RAM arrays for<br />

low latency, deterministic execution<br />

of high priority events<br />

and interrupts.<br />

The production released version<br />

of the IP core is available<br />

immediately for licensing, and<br />

the I7200 is gaining widespread<br />

support among MIPS partners<br />

and customers.<br />

High Performance 2 GHz Sector Antennas for LTE Networks<br />

KP Performance Antennas announced<br />

that it has released a new line of highperformance,<br />

2 GHz sector antennas for<br />

use in WISP networks. KP’s new line of<br />

LTE (Long Term Evolution) 2 GHz sector<br />

antennas consists of three new models:<br />

KP-2DP120S-45, a 14 dBi sector with<br />

120° azimuth beamwidth, the KPPA-<br />

2GHZDP60S-17-45, a 15.1 dBi sector<br />

with a 60° azimuth beamwidth, and the<br />

KPPA-2GHZDP90S-45 which provides<br />

17 dBi of gain with a 90° azimuth beamwidth.<br />

These 2 GHz sector antennas utilize<br />

a ±45° slant dual polarization scheme<br />

and are specially designed with optimized<br />

front to back and side lobes that allow for<br />

frequency reuse. These antennas feature<br />

heavy-duty weatherized sector brackets,<br />

select models also include jumper cables<br />

and radio brackets. These LTE sector<br />

antennas also deliver high-gain in a compact<br />

shell for ease of deployment. All<br />

models in this line operate in the popular<br />

2.3 to 2.7 GHz frequency range and deliver<br />

SWR from 1.3 to 2.<br />
