Method to characterize the prospective or actual level of interference at a point, in a sector, and throughout a cellular system

A computer implemented process compares signals communicated between a known position and a plurality of base stations in a cellular telephone system to determine the level of interference with a signal on a channel expected to serve the known position, and determines a value indicating a probability of interference with a signal on a channel expected to serve the known position.

Method and apparatus for predicting the effective addresses of future memory load operations in a microprocessor

Номер: US5210838A
Автор: Eric H. Jensen

A method and apparatus for loading a data value for a future LOAD instruction in a microprocessor by predicting the LOAD instruction's effective address. At each occurrence of a LOAD instruction, the effective address used is stored in a memory array which stores a last effective address and a next-to-last effective address. At a specified period before each LOAD instruction, the microprocessor loads a data value from a predicted effective memory address computed from the memory array. The predicted effective memory address is equal to the last effective address plus the difference between the last effective address and the next-to-last effective address. If the predicted effective address equals the actual effective address of the future LOAD instruction, the loaded data value is used.

Page-tagging translation look-aside buffer for a computer memory system

Номер: US5133058A
Автор: Eric H. Jensen
Принадлежит: Sun Microsystems Inc

A caching memory system including a translation look-aside buffer having a preselected number of lines of memory, each of said lines including storage for a virtual address and a physical address, apparatus for selectively varying the size of pages the virtual and physical addresses of which may be stored in the translation look-aside buffer, and apparatus for interrogating the virtual addresses to determine whether a requested address is stored in the translation look-aside buffer.
