Prompted by the chipmaker's announcement of the SSE5 instruction-set extensions, Glaskowsky analyzes the ultimate outcome to this old controversy. Peter N. Glaskowsky is a computer architect in ...

Try to investigate the differences between the x86 and ARM processor families (or x86 and the Apple M1), and you'll see the acronyms CISC and RISC. It's a common way to frame the discussion, but not a ...

As the demand for high-performance processors continues to grow and semiconductor scaling laws continue to show their limits, the need for processor optimization is inevitable. As I explained in a ...

In a previous post, we considered how you could create an optimized ISA for a domain-specific processor core by profiling software and experimenting with adding/removing instructions. Using the open ...

Whenever you think of mobile computing hardware, Arm is likely the first company that comes to mind, or it should be. While historically Intel has been recognized as the leader in chip making, for ...
