Ukraine's Zelenskyy at NATO defense ministers meeting seeking support to fight Russia_我的网站
A | 8月26日消息，三星宣布，全球首次研发出面向移动端及端侧AI设备的下一代内存——LPDDR-PIM，该技术将运算功能集成于移动内存中，可有效提升AI处理速度并降低功耗。 BRUSSELS -- For the first time, Ukraine President Volodymyr Zelenskyy joined a meeting of more than 50 defense leaders from around the world Wednesday to make a personal pitch for military aid, in the face of lagging political support in the U.S. and new pressure on allies to send weapons to bolster Israel’s war with Hamas.His presence underscored growing concerns about cracks in what has been staunch international backing for Kyiv in its war against Russia's invasion, and worries that Ukrainian forces haven't made measurable progress in the counteroffensive, as winter closes in.“Next Monday, we will mark the 600th day of our resistance to Russia’s full scale aggression against our people, against Ukraine. And today, no one can say for sure how many more days we will have to defend our independence and to defend our identity,” Zelenskyy told the gathering as they opened the meeting. “But we can already say several things which I think are important. First, Putin will not achieve Ukraine. Second, Russia cannot afford a new arms race. And third, democracy can win this battle.”The meeting of the Ukraine Defense Contact Group, hosted by the U.S., comes as Ukraine is desperately seeking more weapons to help its troops regain ground from Russian forces before the muddy weather sets in. But political chaos in Congress stalled approval of new Ukraine funding, and there has been growing opposition among some lawmakers to any increase in spending. Speaking as he entered NATO headquarters, Zelenskyy noted the Israel war, and said Ukrainians understand such tragedy. But he was also quick to detail Ukraine's ongoing need for air defense systems and long-range missiles “to push Russia out of our land.”U.S. Defense Secretary Lloyd Austin told reporters traveling with him to Brussels that support for Ukraine continues unabated. He said a number of allies will announce they are sending additional weapons and other support to Kyiv. A key demand has been more air defense systems and munitions.“The energy, in my view, is still there,” said Austin. “And I will reassure them that we remain committed to this.”He echoed those thoughts as he opened the meeting, asserting that Ukraine is making steady progress in the war. And he said allies during this meeting will focus not only on meeting Kyiv's immediate needs but also on setting up plans to coordinate investments in Ukraine's future forceThe contact group is the main forum for raising contributions of weapons, equipment and training for Kyiv’s war effort. It meets about once a month, in person and virtually, and this is the 16th gathering.Zelenskyy, who was greeted with applause as he entered the building, went immediately into a private session with Austin and U.S. Air Force Gen. CQ Brown, chairman of the Joint Chiefs of Staff.Speaking to reporters as he came in, Zelenskyy reiterated his country's need for long-range missiles and ammunition.“It’s very important that there are priorities. There are air defense systems. These are not just basic words. These are very concrete things and we need them,” Zelenskyy said.Following that meeting, the 31 allies and Ukraine will take part in the first NATO-Ukraine Council at this level. The forum was formally established in July as part of efforts to bring Kyiv closer to the alliance. It allows NATO and Kyiv to discuss issues of common interest and concern.The new package of U.S. aid includes AIM-9M missiles for air defense, counter-drone systems, munitions for the High Mobility Artillery Rocket System (HIMARS), artillery, electronic warfare equipment, demolition munitions, anti-armor systems and more than 16 million rounds of small arms ammunition.The weapons are provided under presidential drawdown authority, so will be taken from Pentagon stocks and delivered quickly to the battlefield. ___Follow AP’s coverage of the war in Ukraine at https://apnews.com/hub/russia-ukraine。
在美国斯坦福大学举行的半导体学术会议Hot Chips 2026上，三星相关负责人首度公开展示了LPDDR5X-PIM的结构、规格及验证结果——该产品本月初刚在FMS 2026内存会议上斩获下一代内存奖项，但详细参数直到此次会议才正式披露。 PIM（内存内运算）技术通过在内存中嵌入运算单元，使部分计算可直接在内存内部完成，无需像传统架构那样将数据频繁搬运至CPU或GPU再传回内存。 对于AI运行而言，数据搬运是主要性能瓶颈之一，应用PIM后，简单运算就近处理，从而在提升速度的同时显著降低功耗。

在测试环节，三星以参数规模达80亿的Meta开源AI模型Llama 3.1为基准，结果显示LPDDR5X-PIM的处理时间为5.4秒，较普通LPDDR5X的12.3秒快了约2.3倍；每秒令牌处理量达81.3 TPS，为现有产品27 TPS的三倍。 事实上，三星早在2021年便公布了面向高带宽内存的HBM-PIM技术并完成开发验证。此次将PIM落地于智能手机等移动设备广泛采用的LPDDR低功耗内存，正是顺应大语言模型向小型化、高效化演进的新趋势。
C | 相关负责人指出，虽然HBM是目前AI内存的标准方案，但并非所有场景都非它不可，LPDDR-PIM兼具高带宽与低功耗，为端侧AI开辟了新的可能。

随着生成式AI直接在智能手机、PC等终端设备上运行的端侧AI趋势不断扩展，LPDDR-PIM的应用前景持续看涨——电力与空间受限的移动设备，亟需在提升AI算力的同时严控功耗。 在兼容性方面，该产品沿用与通用LPDDR相同的阵列设计，无需大幅改动系统即可部署。
E | 目前，三星正提供软件开发工具包和模拟器等资源，积极推动生态建设。
F | 继LPDDR5X-PIM之后，三星已启动LPDDR6-PIM的标准化工作，AI内存竞争正从以HBM为中心的数据中心，延伸至智能手机和PC等端侧领域，内存也正从单纯的数据存储设备，向直接参与运算的关键组件演进。
