Abstract : This report analyzes selected hardware enhancements that could improve the performance of the 9020 computer systems, which are used to provide en route air traffic control services. These enhancements could be implemented quickly, would be relatively inexpensive, and would provide a solution to the short-term but not the long-term problems that the system faces. Three memory enhancements are discussed. First, the storage element (SE) memory boxes could be replaced. Second, the memory stacks in the SE's could be replaced. Third, the memory stacks in the input-output control elements (IOCE's) could be replaced. Three processor enhancements are discussed. First, the processors in the compute elements (CE's) could be sped up. Second, the processors in the IOCE's coulde be sped up. Third, the CE's could be replaced.
