Collaborate Disseminate
Until the early 2000s, the computer processors available on the market were essentially all single-core chips. There were some niche layouts that used multiple processors on the same board for …read more Continue reading The ’80s Multi-Processor System That Never Was
You know things are getting real when the Dremel is one of the first tools you turn to after unboxing your new oscilloscope. But when your goal is to hack …read more Continue reading Hacked Oscilloscope Plays Breakout, Hints at More
For example considering that ARM has TrustZone technology, and a potential reduced attack vector because it is based on a simpler RISC (Reduced Instruction Set Computing) based architecture instead of the CISC (Complex Instruction Set Comp… Continue reading In general terms does the use of ARM architecture pose any security benefits or risks over other architectures such as x86 and x64?
There are a ton of inventions out in the world that are almost complete accidents, but are still ubiquitous in our day-to-day lives. Things like bubble wrap which was originally …read more Continue reading How IBM Stumbled Onto RISC
If you have ever wanted to implement a RISC-V CPU core in about 600 lines of C, you’re in luck! [mnurzia]’s rv project does exactly that, providing a simple two-function API. …read more Continue reading A 32-Bit RISC-V CPU Core in 600 Lines of C
We’ve often heard that modern x86 CPUs don’t really execute x86 instructions. Instead, they decode them into RISC instructions that are easier to schedule, pipeline, and execute. But we never …read more Continue reading Behind the x86 Pipeline Curtain
Over Apple’s decades-long history, they have been quick to adapt to new processor technology when they see an opportunity. Their switch from PowerPC to Intel in the early 2000s made …read more Continue reading The Apple Silicon That Never Was
[RetroBytes] nicely presents the curious history of the SPARC processor architecture. SPARC, short for Scalable Processor Architecture, defined some of the most commercially successful RISC processors during the 1980s and …read more Continue reading History of the SPARC CPU Architecture
It is interesting how, if you observe long enough, things tend to be cyclical. Back in the old days, some computers didn’t use binary, they used decimal. This was especially …read more Continue reading The 10 Kinds of Programmers That Use Calcutron-33
MikroLeo is a discrete TTL logic-based microcomputer intended for educational purposes created by [Edson Junior Acordi], an Electronics Professor at the Brazilian Federal Institute of Paraná, Brazil. The 4-bit CPU …read more Continue reading MikroLeo, A 4-Bit Retro Learning Platform
