Getting It Right

Something had to be done to get the project on track. The team was reorganized, and, in spite of looming deadlines, made smaller. Chris was not replaced. Fred moved off to a different project. Willis and Henry moved off to a different 777 support role, working with the C compiler that was used for a small portion of the 777 code. Peter, an additional consultant from DDC-I, was added. Tom officially took over as project lead. The team divided the work not previously done, identifying the unique features of the processor that affect code generation and the runtime implementation. The frontend of the compiler could be used without change. Only a very small amount of the code generation and a minimal amount of the runtime are necessary to compile and run "Hello World". Though it was close, the first deadline was met.

Following this, some team members began the detailed design and implementation of the storage management, task management, and exception management of the runtimes. Others continued with more code generation.

Waleen did the design and implementation of storage management. At a high level, many of the algorithms could be similar to those used for the I960. The biggest challenge was that this was being written in assembly language, so a complete rewrite needed to be done. Waleen also had to learn the assembly language.

A low-level body of code called the User Configurable Code (UCC) allows for the writing of a very small portion of code to allow interfacing ...
