In a systems programming interview, one of the fastest ways to separate an “Application Developer” from a “Systems Architect” is to ask where a specific variable lives. In the embedded …

In a standard software interview, volatile is often described simply as “telling the compiler not to optimize a variable.” But for a System Architect or an Embedded Lead, that answer …

The modern SoC is no longer just a CPU and a GPU. To meet the demands of real-time vision, voice, and predictive maintenance, we are integrating specialized Neural Processing …

In the semiconductor industry, a chip that works in the lab but fails in a data center is a liability. As a System Architect, your design is only as …

In the semiconductor world, we no longer assume the Operating System is a safe haven. If a kernel driver is compromised (as we saw in our debugging series), the …

In the previous articles, we focused on the “brain” (the CPU) and its local memory. But in modern system design—especially for hyperscale data centers and AI clusters—the bottleneck isn’t …

In the semiconductor world, performance is no longer limited by how many transistors we can fit on a chip, but by how much heat we can dissipate. This is …

In system design, there is no such thing as a “fast” system in a vacuum. There are systems that process massive amounts of data (High Throughput) and systems that …

In modern system design, the CPU is often a victim of its own speed. While processor frequencies have scaled into the GHz range, external DRAM remains orders of magnitude …

In the semiconductor world, “Power-On Reset” (POR) is the moment of truth. For a System Architect, the boot flow is not just about loading an OS; it is a …
