Building Superior Embedded Systems
The Intel 8086 was a 16-bit microprocessor that was launched in 1978 and retired in 1998. The 8086 is one of the most influential processors ever created because it introduced the x86 processing architecture and instruction.
A context switch is the process of storing the state of a process, thread, or processor operating mode so that it can be restored at a later point to resume execution.
ARM Processor Register. The CPSR holds information about the most recently performed ALU operation , controls the enabling and disabling of interrupts , and sets the processor operating mode.
A multiprocessor computer system where not all of the multiple interconnected central processing units (CPUs) are treated equally.
A multiprocessor computer hardware and software architecture where two or more identical processors are connected to a single, shared main memory, have full access to all input and output devices, and are controlled by a single operating system instance that treats all processors equally, reserving none for special purposes. Most multiprocessor systems today use an SMP architecture.
“AP” can refer to “Application Processor” or “Access Point” (for Wi-Fi).
Secure Processing Environment
Debugging a processor using circuitry embedded in a chip, as opposed to in-circuit debugging.
Imprint Lithography
Refers to the capability for a processor to run a program directly from ROM (such as Flash). Processors without XIP capability must copy the entire program to memory before it can run.
