ABSTRACT:
A method of allocating memory in a data processing system10and a memory allocation mechanism54are provided. Memory is allocated by the memory allocation mechanism in response to a memory allocation request56from a process50running on the system10. The request56includes data identifying the size of the block required and an indication of a mask bit pattern. The memory allocation mechanism receives the request, selects a block of memory having an appropriate size and having an address with a bit pattern which corresponds correctly to the indicated mask bit pattern, and allocates the selected block of memory to the process.
