2.1.4 Processes and the memory model

ATPCS applies to a single thread of execution or process. The memory state of a process is defined by the contents

of the processor registers and contents of the memory that it can address.

A process can address some or all of these types of memory:

• Read-only memory.

• Statically-allocated read-write memory.

• Dynamically-allocated read-write memory. This is called heap memory.

• Stack memory. See The stack.

A process must not alter the memory state of another process unless the two processes are specifically designed to

cooperate.
