Multithread programming.† There are basically two thread scheduling rules. The first rule is that if a higher priority thread becomes ready, the running thread is preempted. The second rule is that threads having the same priority are scheduled in a first-in first-out fashion. Three ...
It is much easier to maintain a program in C than in Assembler and the penalty of larger, slower programs is not as severe as with some other high-level programming languages. We will discuss the various trade-offs between different programming languages later in Chapter 13. Show moreView ...

Figure 3.46.When the application code starts to run it must relocate the vector table to the start of the application code by programming the NVIC vector Table Offset register. The Vector table can be relocated by writing to a register in the NVIC called the “Vector Table Offset” register....
OpenAMP can handle interrupts, access devices, and manage the memory using the Libmetal library. This library also provides Application Programming Interfaces (APIs) for synchronization primitives. There are three fundamental modules in the OpenAMP architecture which use Libmetal and are implemented in the...
