Corbett, D. Saslav 12-15 weeksThis project is intended as a part of the effort to port the Lambda operating system to the Falcon. A detailed analysis of all Lambda microcode is required to classify each microcode routine into one of the following categories: % Performance optimizations; % Standard primitives; % Hardware dependencies; % Portable routines; % Asynchronous routines. Having achieved such a classification for each microcoded routine, it will then be possible to determine exactly how to go about rewriting some of these modules to ensure a smooth inter-machine port and a robust final product. Justification: Equivalent microcode is not provided on the Falcon. As a result, an project of this kind is the only possible avenue for exploring low-level inter-machine compatibility issues from a personnel/scheduling perspective. I. Lambda performance optimizations: These microcode routines are Lambda-specific and will not be required for the Falcon. II. Standard Common LISP primitives: These are functions, macros, and other definitions which already have microcode implementations for the Falcon. No (for which equivalent Falcon assembler routines are needed) (those which can be reimplemented using LISP primitives) (e.g., the trap handler) which may or may not require portingrewrite on the Falcon.

Assuming that all such implementations pass the requisite suite of Common LISP tests, no further work will be required to ensure proper Falcon functionality for these definitions. III. : These are the LISP definitions which have been implemented in a processor-dependent fashion, and f. In each such case, careful analyses of the nature of the hardware dependence and the means by which equivalent Falcon routines could be written are required. IV. : These are the LISP definitions which have been implemented in a non-processor-dependent fashion, in adherence with the guidelines set forth by the Common LISP specification. Once the definitions of Group II (standard Common LISP primitives) have been ported, the definitions of Group IV should port without further human effort. V. : These are routines which have been written to handle inter-process and extra-machine interactions on the Lambda . Some of these may require porting to the Falcon, and some may not. Those asynchronous routines requiring porting must be identified and analyzed from a hardware perspective, to ensure correct Falcon behavior, analyzed from a software perspective for portability considerations, and then rewritten or simply ported mechanically (depending on the results of the aforementioned software analysis).Analyze and classify all microcoQ?
