The space complexity of an algorithm or a data structure is the amount of memory space required to solve an instance of the computational problem as a function of characteristics of the input. It is the memory required by an algorithm until it executes completely. [1] This includes the memory space used by its inputs, called input space, and ...
In software engineering, a unity build (also known as unified build, jumbo build or blob build) is a method used in C and C++ software development to speed up the compilation of projects by combining multiple translation units into a single one, usually achieved by using include directives to bundle multiple source files into one larger file.
The amount of memory needed for the input data. The amount of memory needed for any output data. Some algorithms, such as sorting, often rearrange the input data and do not need any additional space for output data. This property is referred to as "in-place" operation. The amount of memory needed as working space during the calculation.
Loop unrolling, also known as loop unwinding, is a loop transformation technique that attempts to optimize a program's execution speed at the expense of its binary size, which is an approach known as space–time tradeoff. The transformation can be undertaken manually by the programmer or by an optimizing compiler.
A register that holds the result of previous operation in ALU. It can be also used as an input register to the adder. address The unique integer number that identifies a memory location or an input/output port in an address space. address space A mapping of logical addresses into physical memory or other memory-mapped devices.
Executable space protection is an approach to buffer overflow protection that prevents execution of code on the stack or the heap. An attacker may use buffer overflows to insert arbitrary code into the memory of a program, but with executable space protection, any attempt to execute that code will cause an exception.
Use of a Bloom filter for this purpose, however, does increase memory usage [citation needed]. While risking false positives, Bloom filters have a substantial space advantage over other data structures for representing sets, such as self-balancing binary search trees , tries , hash tables , or simple arrays or linked lists of the entries.
Address space layout randomization (ASLR) is a computer security technique involved in preventing exploitation of memory corruption vulnerabilities. [1] In order to prevent an attacker from reliably redirecting code execution to, for example, a particular exploited function in memory, ASLR randomly arranges the address space positions of key data areas of a process, including the base of the ...
