中国新歌声

一 |     Beijing/London, Oct 18 (UNI) China's foreign ministry has defended an incident in which a Hong Kong protester was pulled into Chinese consulate grounds in the British city of Manchester and beaten up.

A spokesman said people had "illegally entered" the grounds and any country's diplomats would have taken "necessary measures" to protect their premises, the BBC reported.

On Tuesday, Hong Kong leader John Lee weighed in on the event, saying it should be dealt with in accordance with local laws.

Police are investigating an assault on the pro-democracy protester on Sunday. Footage shows men emerging from the consulate and dragging a man inside.

The violence has prompted loud calls for the UK government to summon China's ambassador, and possibly take further action.

The protester, identified as Bob, suffered several physical injuries and spent a night in hospital for treatment.

However, China is sticking to a different version of events from the police.

"People [who] intended to cause nuisance entered the Chinese Consulate-General in Manchester illegally... threatening the safety of a Chinese diplomatic facility," said foreign ministry spokesman Wang Wenbin at a daily press briefing in Beijing.

He added that any attempt to infringe on the consulate's "tranquillity and dignity" would "not be tolerated".

According to a statement by the Greater Manchester Police, around 30 to 40 people had gathered outside the consulate and patrols were in the area to help maintain the "peaceful protest".

"Shortly before 4pm a small group of men came out of the building and a man was dragged into the consulate grounds and assaulted," a police statement said.

"Due to our fears for the safety of the man, officers intervened and removed the victim from the consulate grounds."

The consulate says protesters had displayed an insulting portrait of China's president.

Bob told BBC Chinese that "mainlanders" - people from mainland China, as opposed to Hong Kong - had come out of the consulate and destroyed their posters.

"As we tried to stop them, they dragged me inside, they beat me up," he said. "It's ridiculous. They [the attackers] shouldn't have done that. We are supposed to have freedom to say whatever we want here [in the UK]."

The protest took place on the same day China kicked off its twice-a-decade Communist Party Congress, where its leader President Xi Jinping is widely expected to secure a third term in power.

Xi had on Sunday made reference to the situation in Hong Kong, saying Beijing had turned the situation in the city from "chaos to governance".

Beijing imposed a sweeping national security law on the former British colony after pro-democracy demonstrations in 2019.

UNI ING。    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。

    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。    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。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。    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。
