Stack machine. In computer science, computer engineering and programming language implementations, a stack machine is a computer processor or a virtual machine in which the primary interaction is moving short-lived temporary values to and from a push down stack. In the case of a hardware processor, a hardware stack is used.
The Burroughs Large Systems Group produced a family of large 48-bit mainframes using stack machine instruction sets with dense syllables. [NB 1] The first machine in the family was the B5000 in 1961, which was optimized for compiling ALGOL 60 programs extremely well, using single-pass compilers. The B5000 evolved into the B5500 (disk rather ...

How do stack machines work?
• This stack machine (like the previous) can pop the S off the top of the stack at any time • But there is only one correct time: it must be popped off in the middle of the input string • This uses the nondeterminism of stack machines • We can think of these machines as making a guess about where the middle of the input is
Stack Machines • Stacks are ubiquitous in computer programming, and they have an important role in formal language as well. • A stack machine is a kind of automaton that uses a stack for auxiliary data storage. – The size of the stack is unbounded—it never runs out of space—and that gives stack machines an edge over finite
We will now define a new computational model, the stack machine model, and ob-serve that it is equivalent in power to the deterministic Turing machine model. There are two principal motives behind the introduction of the stack machine model at this point in the course: 1.Stack machines are easier to work with than Turing machines, at least at ...
Stack Machines •Location of the operands/result is not explicitly stated –Always the top of the stack •In contrast to a register machine –add instead of add r 1, r 2, r 3 –More compact programs •One reason that Java bytecode uses stack evaluation
In computer science, a stack machine is a model of computation in which the computer's memory takes the form of one or more stacks This short article about technology can be made longer. You can help Wikipedia by adding to it .
