The original JAM emulator was first implemented by Mike Williams (the
instruction set was argued out with Joe Armstrong).

The original BEAM emulator and loader were first implemented by Bogumil Hausman.
They were completely rewritten by Björn Gustavsson.

Over the years the emulator has been basically completely rewritten by
a large number of individuals. Most(?) notably Claes Wikström, Tony
Rogvall, Björn Gustavsson, Patrik Nyblom, Rickard Green, Raimo Niskanen
and Arndt Jonasson.

Marcus Arendt did the original port for Windows NT. Most of this code
was rewritten by Björn Gustavsson, Patrik Nyblom, Kenneth Lundin,
Fredrik Tillman and Mattias Nilsson.

Per Hedeland did the original port for VxWorks. This port was
improved by Peter Högfeldt, Patrik Nyblom and Patrik Winroth.

Mikael Pettersson, of the HiPE project, designed and implemented
the new 2-bit tag scheme.

The SMP support has mainly been designed and implemented by Rickard Green,
Tony Rogvall (mostly ets), Mikael Pettersson (mostly optimized synchronization
primitives, and timer thread), and Patrik Nyblom (mostly dynamic drivers, and
Windows port). Also Björn Gustavsson and Raimo Niskanen have contributed.

There are also a lot of people who have contributed smaller (and
bigger) things to the emulator and runtime system: Per Hedeland,
Peter Högfeldt, Kenneth Lundin, Fredrik Tillman, Mattias Nilsson,
Kent Boortz, Markus Torpvret, Jan-Erik Dahlin, Sebastian Strollo
and perhaps more...

Björn Gustavsson (mostly matching) and Arndt Jonasson (mostly construction)
implemented the bit syntax instructions, borrowing some code from
the original prototype implementation by Tony Rogvall and Claes Wikström.

The HiPE project (Kostis Sagonas, Mikael Petterson, Erik Johansson,
Richard Carlsson, Ulf Magnusson, Jesper Wilhelmsson) added the
hipe runtime to the Beam emulator. Björn Gustavsson helped to
integrate the hipe runtime.

Rickard Green has designed and implemented the erts_alloc framework and
memory allocators.

Per Gustafsson (and perhaps others in the HiPE group) come up with
idea for bit-level binaries and binary comprehensions. Per Gustafsson
and Björn Gustavsson implemented them in the BEAM compiler and run-time
system. Björn Gustavsson implemented the new optimizations for matching
and appending of binaries in BEAM compiler and run-time system, while
Per Gustafsson implemented the optimizations in the HiPE compiler and
HiPE run-time system.

The big heap-fragment-elimination project has been going on for many
years and several releases, and was finally finished in R12B. Suggested
by the HiPE group in order to support constant pools and possible
future GC improvements, most of the work was carried out by
Björn Gustavsson, with help from Mikael Pettersson and the HiPE group.

Original Authors:
This asn.1 application was created by
Kenneth Lundin (kenneth@erix.ericsson.se)
with help from Esko Vierumäki.
The work was initially inspired by a previous ASN.1 compiler for Erlang
written by Claes Wikström.
Version 1.1.1 - 1.2.6

compiler

The original JAM compiler was first implemented by Joe Armstrong.

The original BEAM compiler (v1) was first implemented by Bogumil Hausman.

The original v2 and v3 compilers were implemented by Robert Virding.
Björn Gustavsson adapted the code generation for the BEAM machine and
added the optimisation passes.

General improvements and corrections were made by Robert Virding,
Arndt Jonasson, Tony Rogvall, Björn Gustavsson and Jan-Erik Dahlin.

The bit syntax support was implemented by Björn Gustavsson, Arndt Jonasson
and Robert Virding.

The Core Erlang is used as an intermediate format in the v3 compiler (R7).
Core Erlang was suggested by Richard Carlsson (HiPE).

The new inliner in R8 is written by Richard Carlsson (HiPE).

Updates, extensions, and bugfixes in the R8 compiler were made by Robert Virding,
Richard Carlsson (HiPE), and Björn Gustavsson.

Bjorn Gustavsson and Raimo Niskanen implemented the beam_validator compiler
pass for R10B-2 (it makes that the compiler did not generate code that could
crash the run-time system).

The current maintainer of the compiler is Bjorn Gustavsson. To the R12B he
added a simple form of stack trimming, as well as other optimizations.
