In this series, I’ll share all I know about Computer Architecture, breaking down complex concepts into clear explanations, practical foundations, advanced techniques, and real-world approaches for designing secure, high-performance systems.
Modern software performance depends heavily on how efficiently memory is accessed, and not just on raw CPU speed. Sequential memory access tends to be much faster than random access, and understanding why requires a deeper look inside the memory subs...
Modern software performance is deeply influenced by how efficiently memory is accessed. The full story of memory access latency involves multiple layers → from CPU caches to virtual memory translation, and finally to physical DRAM. This article expla...
Software performance is deeply influenced by how efficiently memory is accessed. The story behind memory access latency is layered: it begins with CPU caches, traverses through virtual memory translation, and ultimately reaches physical DRAM. Each la...
Modern multi-core CPUs depend on caches to accelerate memory access and improve performance. However, when multiple cores cache the same memory address, maintaining a consistent view of memory across all cores and main memory (known as cache coherenc...
The key to modern processors’ speed lies in their ability to execute many instructions in parallel, and the foundation for that is a technique called pipelining. Though introduced decades ago, pipelining remains central to how today’s CPUs achieve hi...
For many years, improving CPU performance meant increasing clock speed → allowing more cycles per second. But today, we’ve reached practical limits in how fast we can push frequency due to power, heat, and physical constraints. As a result, modern CP...
