How many billions of transistors in your iPhone processor?

In about 10 years, Apple has multiplied by 19 the number of transistors in its mobile processors. It corresponds roughly to a steady rate of improvement of 34% per year on the number of transistors, or a doubling every 2.5 years. In real dollars, an iPhone has roughly a constant price: the price tag of a new iPhone increases every year, but it does so while tracking the inflation. Thus you are getting ever more transistors in your iPhone for the same price.

Arm Announces Total Design: Taking Neoverse CSS Forward

We recently covered the announcement of Arm’s Neoverse CSS Genesis N2 platform, a near off-the-shelf compute subsystem design created to accelerate the time to market for custom accelerators in leading edge infrastructure. We commented at the time that we…

Clang 如何支持 CUDA 程序

前言

编译 CUDA 程序的主要工具是 NVIDIA 提供的闭源编译器 NVCC，但实际上，NVCC 是基于 LLVM 开发的（来源：NVIDIA CUDA Compiler），NVIDIA 也把 NVCC 其中一部分逻辑贡献给了 LLVM 上游，使得 Clang 也可以在 CUDA 的配合下编译 CUDA 程序。这篇博客尝试研究 Clang/LLVM 如何实现 CUDA 程序的编译，主要是 Clang 前端部分，后端部分，也就是从 LLVM IR 到 NVPTX 的这一步还没有进行深入的研究。

Randomness in programming (with Go code)

Computer software is typically deterministic on paper: if you run twice the same program with the same inputs, you should get the same outputs. In practice, the complexity of modern computing makes it unlikely that you could ever run twice the same program…

Zen 5’s Leaked Slides

A YouTuber called Moore’s Law is Dead recently leaked a couple AMD slides about Zen 5. I typically find leaks uninteresting as they are impossible to verify and often don’t correspond to reality. One example is leakers expecting RDNA 3 to one-up Nvidia’s…
