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 />
