全球首款双架构CPU！IBM同一核心原生跑Arm和Z：2nm、5.7GHz_我的网站

一 |     8月25日消息，IBM在Hot Chips 2026大会上公布了全球首款双指令集架构处理器，在同一核心中原生支持Z和Arm两种架构的软件执行。     这项设计的核心思路不是像Intel的P核和E核那样在芯片上放置两种不同核心，也不是通过模拟层转译，而是将Arm的AArch64指令集直接集成进大型机核心。         实现层面，Arm采用小端序，Z架构采用大端序，两种模式在同一核心内共存。    Singapore, Oct 13 (UNI) Singapore has jailed and fined an OnlyFans creator, in the city-state's first conviction of users of the adults-only platform.

A court on Wednesday fined Titus Low S$3,000 ($2,087) for sharing obscene photos and videos on the site, BBC reported.

He was also sentenced to three weeks prison for accessing his account in breach of a police order.

The case has sparked alarm over the criminal implications for OnlyFans creators in the conservative nation.

In Singapore, it is illegal to transmit obscene materials by electronic means or to take part in or receive profits from a business where such materials are transmitted.

"For sure, this case has set (a) precedent and other users will have to deal with the same risk of being on OnlyFans," Low's lawyer Kirpal Singh told the BBC.

"I think the message is quite clear that authorities are prepared to convict those who transmit explicit material not just on the OnlyFans platform but on the whole spectrum (of online areas)."

Singh said he had been approached by other content creators this year concerned about their own potential criminal liability.

However, experts had earlier suggested that prosecutions against such local content creators appear to only come about if instigated by a third party.

The BBC has reached out to the US-based company which enables users to buy exclusive, often explicit, content from "creators" they subscribe to.

Low was arrested in December 2021 after a woman found one of his explicit videos on her 12-year-old niece's phone and filed a police complaint.

The 22-year-old model had joined the platform only a few months earlier in April, where he had quickly become one of its biggest local stars, the report said.

After the complaint was made, officers confiscated his phone, iPad and changed the details of his OnlyFans account. But Low regained access to his account and continued uploading content as well as starting a second account.

He told the BBC last year he had continued using the site because it was his chief source of income.

Low had faced up to three months jail for sharing explicit pictures, and up to six months for defying the police instruction.

Following his conviction on Wednesday, he posted on Twitter he was "glad this is finally over".

Low, who has over 210,000 followers on social media, is a well-known Singaporean influencer and his case had been highly publicised.

The number of OnlyFans creators in Singapore is unknown but estimated to be in the hundreds.

UNI MR。分支预测单元大量复用了现有Z核心的设计，通过Arm的XML架构描述文件自动生成解码逻辑，寄存器重命名机制为GR16-31范围做了适配，还新增了SVE数据流和FP16、Bfloat16及加密运算的支持。

三 |               IBM在该处理器上实现了完整的AArch64 v9.3架构，支持SVE和SVE2指令，共2792条Arm指令，比Z自身的指令集还多出一倍。IBM在演讲中还打趣说，RISC“精简”一词已经名不副实了。         芯片规格方面，下一代IBM Z处理器采用2nm工艺制造，配备11个核心，基础频率5.7GHz以上，每个核心拥有36MB私有L2缓存，11个核心的L2组合形成432MB虚拟L3，全部核心的L4缓存合并后总容量达3.5GB。              核心采用SMT2同步多线程设计，针对交易和数据库等企业负载做了低延迟优化，还集成了专用片上DPU负责I/O加速，以及AI、压缩、加密和排序加速器。

四 |     这些加速单元以Linux平台设备的形式向Arm生态开放，Arm程序调用加密和压缩功能时延迟与Z原生指令接近。    可靠性方面，Z系统延续了99.999999%的可用性目标，涵盖阵列和数据流的错误检查、瞬态故障透明恢复、永久故障的核心热备和在线修复，以及RAIM内存保护。

五 |          IBM表示芯片已进入流片阶段，距离量产还有几年时间。    至于IBM为何要做这颗芯片，其实也很简单，目前全球前100大银行中有77家在使用IBM Z大型机，将Arm生态引入Z平台，意味着这些客户可以在不放弃大型机可靠性的前提下，直接运行Arm服务器软件和AI推理负载。         IBM还公布了第二代片上AI推理加速器，配备16个活跃AI核心加1个冗余核心，支持FP4和MXFP4数据类型，峰值算力达上一代的4倍。          加速器集成96GB HBM3e显存，带宽约4TB/s，是当前一代的20倍，通过PCIe Gen6与Z处理器实现低延迟对等互联，支持机密计算，在数据存储、传输和使用三个环节提供保护，包括抗量子密码。
