Tham khảo tài liệu 'program c ansi programming embedded systems in c and c++ phần 9', công nghệ thông tin, kỹ thuật lập trình phục vụ nhu cầu học tập, nghiên cứu và làm việc hiệu quả | Part of a software package that is processor- or platform-dependent. Typically sample source code for the board support package is provided by the package developer. The sample code must be modified as necessary compiled and linked with the rest of the software package. breakpoint A location in a program at which execution is to be stopped and control of the processor switched to the debugger. Mechanisms for creating and removing breakpoints are provided by most debugging tools. BACK CONTINUE C CISC Complex Instruction Set Computer. Describes the architecture of a processor family. CISC processors generally feature variable-length instructions and multiple addressing formats and contain only a small number of generalpurpose registers. Intel s 80x86 family is the quintessential example of CISC. Contrast with RISC. CPU Central Processing Unit. The part of a processor that executes instructions. compiler A software development tool that translates high-level language programs into the machine-language instructions that a particular processor can understand and execute. context The current state of the registers and flags of the processor. context switch The process of switching from one task to another in a multitasking operating system. A context switch involves saving the context of the running task and restoring the previously saved context of the other. The piece of code that does this is necessarily processor-specific. counting semaphore A type of semaphore that is used to track multiple resources of the same type. An attempt to take a counting semaphore is blocked only if all of the available resources are in use. Contrast with binary semaphore. critical section A block of code that must be executed in sequence and without interruption to guarantee correct operation of the software. See also race condition. cross-compiler A compiler that runs on a different platform than the one for which it produces object code. A cross-compiler runs on a host computer and .
