Filed: 1990-12-20
Abstract: A hydraulically powered repetitive impact hammer (20) has internal features for ensuring continued automatic repetitive operation under adverse conditions, and fluid cushioning of internal parts to prevent damage from abrupt metal-to-metal contact. The hammer head (31) of the impact hammer (20) has an internal poppet (55) which automatically closes to enable the buildup of pres-sure in a compression chamber during reloading in preparation for the hammer head's next blow (31), and automatically opens to enable the pressure in the compression chamber (47) to drive the hammer head (31) to strike an impact tool (25). To prevent inadvertent stalling of the hammer dur-ing reloading if the impact tool (25) is pressed forcibly into contact with the working face (30) after striking a blow, the amplification ratio of the hammer head (31) is made greater than the amplifica-tion ratio of the poppet (55). Fluid cushioning of the hammer head (31) to prevent abrupt metal-to-metal contact with the frame (21) of the hammer (31) at the end of the driving stroke is provided by a temporary fluid restriction which operates only when the hammer head (31) is near the end of its driving stroke. Fluid cushioning of the poppet (55) to prevent abrupt contact with the hammer head (31) is provided by mating fluid cushioning surfaces (195, 197) formed on the hammer head (31) and poppet (55), respectively, for enclosing fluid in a confined space as the poppet (55) approaches one or the other extremity of its range of movement in the hammer head (31).

Abstract: A fully programmable, graphics microprocessor is disclosed which is designed to be embodied in a removable external memory unit for connection with a host information processing system. In an exemplary embodiment, a video game system is described including a host video game system and a pluggable video game cartridge housing the graphics microprocessor. The game cartridge also includes a read-only program memory (ROM) and a random-access memory (RAM). The graphics coprocessor operates in conjunction with a three bus architecture embodied on the game cartridge. The graphics processor using this bus architecture may execute programs from either the program ROM, external RAM or its own internal cache RAM. The fully user programmable graphics coprocessor has an instruction set which is designed to efficiently implement arithmetic operations associated with 3-D graphics and, for example, includes special instructions executed by dedicated hardware for plotting individual pixels in the host video game system's character mapped display which, from the programmer's point of view, creates a "virtual" bit map by permitting the addressing of individual pixels -- even though the host system is character based. The graphics coprocessor interacts with the host coprocessor such that the graphics coprocessor's 16 general registers are accessible to the host processor at all times.

An optional stacking and fusing procedure is also described to facilitate shipment of frame members prior to assembly.
Patent CA-2088779-A1 (CA)
Inventor: SITES RICHARD L
IPC: G06F12/08
Filed: 1992-05-21
Abstract: A computer system using virtual memory addressing and having a direct-mapped cache is operated in a manner to simulate the effect of a set associative cache by detecting cache misses and remapping pages in the main memory so that memory references which would have caused thrashing can instead coexist in the cache. Two memory addresses which are in different pages but which map to the same location in the cache may not reside in the direct-mapped cache at the same time, so alternate reference to these addresses by a task executing on the CPU would cause thrashing. However, if the location of one of these addresses in main memory is changed, the data items having these addresses can coexist in the cache, and performance will be markedly improved because thrashing will no longer result. For a CPU executing a virtual memory operating system, a page of data or instructions can be moved to a different physical page frame but remain the same virtual address. This is accomplished by simply updating the page-mapping tables to reflect the new physical location of the page, and copying the data from the old page frame to the new one. The thrashing condition is detected and corrected dynamically by latching cache miss addresses and periodically sampling the latch, the remapping pages containing the addresses found upon sampling. The direct-mapped cache must be large enough to hold two or more pages.
