OS - Operating System
SW - Software
HW - Hardware
CPU - Central Processing Unit. A very small pile of interconnected transistors that go off or on and process the incoming instructions requests.
RAM - Random Access Memory. It can be written to, read from and erased too.
Bigger it is, better it is for the CPU and OS. And user.
ROM - Read Only Memory. It can not be written to by user or OS. Usually contains an instruction set.
BIOS - Basic Input Output System. When device is powered on it checks its physical integrity and various settings before it boots into OS.
It can be flushed and updated for better performance and additional HW features.
PCD - Personal Computing Device, a laptop, but with added extras.
FSL - A free-software license is a notice that grants the recipient of a piece of software extensive rights to modify and redistribute that software.
FOSS - Free and Open Source Software
GNU - GPL - GNU is Not Unix, General Public Licence
EOMA - Embedded Open Modular Architecture
RISC-V - The Free and Open RISC Instruction Set Architecture
RISC-V is a free and open ISA enabling a new era of processor innovation through open standard collaboration.
RISC-V ISA delivers a new level of free, extensible software and hardware freedom on architecture, paving the way for the next 50 years of computing design and innovation. That is what BPCD is all about.
ISA - Instruction Set Architecture
RISC - Reduced Instruction Set Computer
SoC - System-on-Chip. One CPU to rule them all.
AMBA - Advanced Microcontroller Bus Architecture is a freely-available, open standard for the connection and management of functional blocks in a System-on-Chip.
SoM - System-on-Module. Systems on a module consist of one or more CPUs and GPUs, but also have connectors for external peripherals and are to be easily exchangeable if put in a proper form-factor.
Think of a card that can be plugged in or taken out.
