Title: Register-cache architecture and super-actor machine
Inventor: HUM HERBERT H J
IPC: G06F9/30
Filed: 1991-09-06
Abstract: ABSTRACT           A  multi-threaded  architecture  having  high  speed memories used with a multiprocessor.  The memories utilized in the processor are organized as both a register file and a cache. A program is compiled into a number of instruction threads called super-actors.  Each super-actor would have a dormant, an enabled, a ready and an active state.  The super-actor becomes ready for execution only when its input data is physically residing in the register-cache and spaces are reserved to store the result.  The invention would operate utilizing either a sequential super-actor which requires that the instructions be sequentially executed, or a parallel super-actor, in which case the instructions are data dependent,  and none of the instructions depend on any results produced by any other instruction within the super-actor. The register file and cache is addresssable based upon the content of its memory locations, when viewed from a main memory, as well as being addressable by its address tags when viewed by a super-actor execution unit.

Abstract: ABSTRACT OF THE DISCLOSURE Electromagnetic relay having a sealed housing.  The relay has a housing with a cap and a bottom part.  The region of the bottom part under the coil winding has a bottom section that is set back in height, as a result whereof the space between the coil flanges and under the winding also becomes accessible from the outside when the relay is attached to a printed circuit board.  The bottom part may potentially have cup-shaped bellied portions as an envelope for the coil flanges.  The joining seam between the at least partially height-offset bottom part and the shortened cap is upwardly displaced in this way from the lower terminating plane at least to the lower apex of the coil winding.          The relay housing can be sealed with casting resin in this joining plane, whereby clearances in the lower terminating plane of the housing as well as in the height-offset joining plane can be sealed in common using a capillary system.  Additional components can be arranged on the printed circuit board in the free space under the winding.  Moreover, the space under the relay is more easily accessible for cleaning the printed circuit board.
Patent CA-2056174-A1 (CA)
Title: Cache controller
Inventor: SHERMIS J HERSCHEL
IPC: G06F9/32
Filed: 1991-11-26
Abstract: A cache controller is coupled between a central processing unit (CPU) and a memory management unit (MMU). The MMU is coupled to main memory, and the cache controller is further coupled to a cache memory. A cache controller transfers a block of N programming instructions from the main memory into the cache memory. Once this transfer is complete, the CPU begins the sequential execution of the N instructions. Generally concurrently, the cache controller scans each of the N instructions to detect branch instructions. Branch instructions are those instructions which require additional data not found within the block of N instructions previously loaded into the cache. Upon detection a branch instruction, and prior to the execution of the branch instruction by the CPU, the cache controller fetches the branch instruction data from main memory, and stores it within the cache.

Multiple user interfaces are established for selected functions within a multiple function application and stored within a data processing  system.  Each of the multiple user interfaces preferably has a different level of complexity.   User profiles  for selected users within the data processing system are then utilized to specify desired levels  of  complexity  for  particular  functions  for  each selected user.  Thereafter, these user profiles are utilized to automatically select a particular one of the multiple user interfaces within a multiple function application in response to a selection of a particular function by a user. In one depicted embodiment of the present invention a user may selectively alter a user profile or alternatively, the user profile may be automatically altered by the occurrence of a selected event, such as the lapse of a selected period of time or the completion of an education course by a user. In either event a default user interface is also provided for utilization in situations wherein a user profile does not specify a desired level of complexity for a selected function.
