Questions tagged [architecture]
As used in EE.SE, it describes the physical topology and techniques of routing power, ground, data and control lines across a given area. This could be a CPU/MPU, circuit board or the lighting of LED's around a pool. Electrical parameters and physical (object) constraints ultimately decide the most efficient and safe layout. The term 'architecture' has no scale (size) until it is defined by schematics, diagrams, blue prints.

How do you fit so many instructions on a 8-bit processor?
I will preface this that it is highly likely that I have misunderstood how Harvard architecture works, but I cannot understand how an 8-bit instruction set, say the ATmega128 for example, can contain ...

How do 16-bit addresses work inside 8-bit data bus processors?
As a project I am building a small 8-bit RISC processor out of discrete ICs. I have 17 instructions and cannot fit all information into instructions that are only one byte, so I have been thinking ...

Why do we see one, unified memory address space in ARM Cortex-M core based MCUs even though they have Harvard architecture?
Most of the ARM Cortex-M core based MCUs have Harvard architecture (except for Cortex-M0 and M0+.)
The thing I do not understand is that why we see only one memory address space. For example, in tge ...

Are coarse-grained reconfigurable architectures a subset of dataflow architecture?
By definition, dataflow architectures consist of large modules in the dataflow path, such as adders and multipliers for integer, floating-point, or fixed-point computation.
Hence, are coarse-grained ...

Power outage detection to kickstart a safe shutdown and data retention process
I plan a system that operates on a 5v rail.
The power is supplied from an outside DC source.
The 5 V powers an RPI CM4 and other components that are controlled by it.
The whole system requires up to 5 ...

Soft errors from SEUs/SETs in early 8-bit microprocessors?
Why is it that soft errors due to single-event upsets/transients never seemed to be a problem in early 8-bit microprocessors, like the MOS 6502 or the Zilog Z80? The microprocessors themselves were ...

What are common ways that modern processors handle data hazards with asynchronous registers
I'm trying to design a processor in VHDL. While the base instruction set is done, I'm having trouble building on top of it.
Specifically, I'm implementing control and status registers (CSRs), which ...

IA 32 architecture segmentation
I was reading the 10th edition of "Operating System Concepts" written by Abraham Silberschatz and many others. It says about IA-32 architecture's segmentation:
