RCOS

Development on RCOS (the MS-DOS version) has finished due to the short lived future of that platform and also its restrictive nature. The current version of RCOS

• uses a priority based, round-robin scheduling algorithm to multi-task pcode programs,
• uses a simple fixed partition memory management algorithm,
• uses a simple file system based on CP/M,
• supports the use of semaphores and shared memory in pcode programs,
• allows the user to specify the number of terminals for I/O,
• animates process and disk scheduling.

RCOS.java

Development on RCOS.java commenced early in 1996 and a very rough alpha version is available that

• has a very rudimentary user interface and animation,
• animates process scheduling,
• uses a simple round-robin scheduling algorithm to multi-task pcode programs,
• supports the use of semaphores and shared memory in pcode programs,
• a CP/M based file system and a fixed partition memory management system have been written but not incorporated, and
• still has the odd bug to be fixed.

The first beta version of RCOS.java is due for completion by the end of 1996.
