  Burroughs B5000 - Wikipedia, the free encyclopedia
The Burroughs B5000 was a series of computers designed beginning in 1961 by a team at Burroughs under the leadership of Robert (Bob) Barton.
In the B5000 stack, this was done by assigning the top two positions of the stack to two registers A and B. Most operations are performed on those two top of stack positions.
Undoubtedly, the direct influence of the B5000 is the current Unisys ClearPath range of mainframes which are the direct descendants of the B5000 and still have the MCP operating system after 40 years of consistent development.

 Online Encyclopedia and Dictionary - Master Control Program
The Master Control Program (MCP) was the operating system of the B5000 and its successors (the Bnm00 series, A Series of the 1980s, to today's Unisys ClearPath machines).
The MCP was the first commercial OS to provide virtual memory and this was supported by the B5000 hardware (for a description of how the virtual memory works, see the B5000 entry).
The article on the B5000 looks at the way dependent processes could be asynchronously run so that many processes could share common data (with the mechanisms to provide synchronized update).

The circuitry of the B5500 was three times faster than that of the B5000, and this increase in speed, coupled with the use of disks in place of drums, made the B5500 a success for the company.
The B5000 at NASA in Huntsville, Alabama was upgraded to a B5500 in November 1964.
The stack architecture introduced in the B5000 meant that simple word-oriented instructions did not need to have an operand field, since the operands were always at the top of the stack.

 Burroughs Large Systems Architecture
The basic premise of this paper is that the architecture of the Burroughs B5000, as introduced twenty-one years ago and as refined some eighteen years ago, still stands as an example of a modern high-level language computer.
The essence of the B5000 design has changed little in the last twenty years, consisting of the hardware stack, the use of descriptors, and special bits to differentiate code and data.
I have attempted to show that the B5000 included many features still considered new, and which only now are appearing in other systems, The operator set level of the B5500 design has, of commercial necessity, remained essentially unchanged.

The B5000 Algol was so much faster than any other compiler in existence, that it was viewed as a program loader instead of a compiler.
Whether this led to the B5000 being a multiprocecessor system or whether the idea came from work done on military computers at Burroughs in Paolii is hard to say.
The purpose of this letter is not to minimize the contribution of Bob Barton to the B5000 or to computer architecture in general.

The development team for the BurroughsB5000 computer system began in the late 1950s with two major design objectives.
The B5000 contained one to eight high-speed, coincident-current, magnetic core modules for multiprocessor operation.
Automatic programming aids of the late 1950s attacked this problem indirectly by providing object code to accomplish the storage and recall functions.) In the B5000, a “pushdown” stack (qv) is employed to eliminate the need for instructions to store or recall intermediate results.

In most cases, there was no way to accidentally refer to a word as a character string, but there were cases, and as a result, security on the B5000 was not as good as it is, for example, in Java (or in later models in the Burroughs product line).
Programs on the B5000 were composes of streams of instructin syllables, where each syllable was 12 bits.
All arithmetic on the B5000 used operands on the stack.

 Stack machines(John R. Mashey)
Machines most commonly called stack machines [Burroughs B5000, HP3000, etc] commonly have ALU operations with no explicit operands, i.e., the operands are implicitly accessed at (or near) the top of the stack.
I always admired the elegance of the B5000, as a machine designed with compilers and OS's in mind; it fit the technology of the day well, but the tradeoffs have changed - code density is not so important, the stack is a bottlneck for very high-performance implementations, and global optimizing technology is widely available.
Kudos to the Unisys (B5000...B6xxx..A-series) line for longevity: not only was the B5000 the first major stack machine, its descendents look like the last remaining general-purpose stack machines.

However, a common theme in Burroughs machines has been the integration of hardware and software design with the consequence of hardware support for software primitives.
An evolution to the basic B5000, the B6500/7500, offers even more hardware assistance to dynamic memory control.
Chapter 16 gives a detailed discussion of the tagged memory (tags identify memory words as data, descriptors, and control words), descriptor formats, the concept of lexical levels in programs, and the corresponding hardware development of display registers.
