Overview

Based upon the industry’s most widely adopted Vector DSP architecture, the CEVA-XC5 DSP vector processor offers the performance, area savings and power efficiency that system designers demand when implementing a broad range of IoT and M2M communication standards.

The CEVA-XC5 combines highly powerful vector capabilities alongside a general computation engine to deliver industry-leading performance and exemplary power efficiency for even the most cost, power and die size constrained devices. It is ideal for applications where the latest LTE Cat-1 or Cat-M1 standards are used concurrently with Wi-Fi 802.11n, PLC, 802.15.4g, ZigBee/Thread, GNSS or any other emerging IoT communications standard (including NB-IoT, LPWAN, or Wi-Fi 802.11ah).

Low-power operation is achieved with the Power Scaling Unit (PSU) that allows the CEVA-XC5 to take advantage of new Cat-M1/NB1 features such as Power Saving Mode (PSM) and extended DRX to further reduce power.

The CEVA-XC5 can address a wide range of applications including wear alone wearables, smart grid, surveillance systems, asset tracking, remote monitoring systems, connected cars and smart utilities.

The CEVA-XC5 offers powerful SW flexibility to highly complex HW accelerators such as CSI processing required in power and cost efficient Gigabit LTE and 5G eMBB UE.

Low Power LTE for IoT: Ubiquitous Coverage with Extended Battery Life

By 2020, ABI Research predicts that there will be more than 45 billion connected devices worldwide. More than half of these devices will incorporate multiple standards in the same device, such as Wi-Fi, 802.15.4g, GNSS and cellular, including the upcoming ultra- low data rate LTE MTC Cat-M. Some of these devices, such as wearables, will only require a battery life of a few days, but others such as asset trackers will demand a battery life of 5-10 years. So how do system designers address these significantly different challenges, while also meeting the stringent cost and power metrics?
