Title: High-performance multi-processor having floating point unit
Inventor: JAIN ANIL
IPC: G06F9/302
Filed: 1991-06-27
Abstract: HIGH-PERFORMANCE MULTI-PROCESSOR   HAVING FLOATING POINT UNIT               ABSTRACT OF THE DISCLOSURE     A pipelined CPU executing instructions of variable length, and referencing memory using various data widths. Macroinstruction pipelining is employed (instead of microinstruction pipelining), with queueing between units of the CPU to allow flexibility in instruction execution times.  A wide bandwidth is available for memory access; fetching 64-bit data blocks on each cycle.  A hierarchical cache arrangement has an improved method of cache set selection, increasing the likelihood of a cache hit.  A writeback cache is used (instead of writethrough) and writeback is allowed to proceed even though other accesses are suppressed due to queues being full.  A branch prediction method employs a branch history table which records the taken vs. not-taken history of branch opcodes recently used, and uses an empirical algorithm to predict which way the next occurrence of this branch will go, based upon the history table.  A floating point processor function is integrated on-chip, with enhanced speed due to a bypass technique; a trial mini-rounding is done on low-order bits of the result, and if correct, the last stage of the floating point processor can be bypassed, saving one cycle of latency.  For CAL type instructions, a method for determining which registers need to be saved is executed in a minimum number of cycles, examining groups of register mask bits at one time.  Internal processor registers are accessed with short (byte width) addresses instead of full physical addresses as used for memory and I/O references, but off-chip processor registers are memory-mapped and accessed by the same busses using the same controls as the memory and I/O.  If a non-recoverable error detected by ECC     circuits in the cache, an error transition mode is entered wherein the cache operates under limited access rules, allowing a maximum of access by the system for data blocks owned by the cache, but yet minimizing changes to the cache data so that diagnostics may be run. Separate queues are provided for the return data from memory and cache invalidates, yet the order or bus transactions is maintained by a pointer arrangement.  The bus protocol used by the CPU to communicate with the system bus is of the pended type, with transactions on the bus identified by an ID field specifying the originator, and arbitration for bus grant goes one simultaneously with address/data transactions on the bus.

Title: Method and apparatus for applying a conditioning agent to a fibrous material and the resulting product thereof
Inventor: LEMAY MARTIN
IPC: D21H13/00
Filed: 1991-12-13
Abstract: ABSTRACT OF THE DISCLOSURE      Method and apparatus for applying a conditioning agent to a fibrous material to impart a desirable property to the material, such as an enhanced hydrophilicity.  The method comprises the steps of depositing wetting agent in a  foamed  condition  on  the  fibrous  material  and establishing a pressure differential across the fibrous material to draw the foam of wetting agent therein.  By this method a non-uniform dispersion of the wetting agent throughout  the  fibrous  network  is  obtained,   the concentration  of  wetting  agent  being  highest  on  the surface of the fibrous material on which the foam is delivered.  As a result, the treated fibrous material has a preferential fluid absorption surface.   The invention also  provides  a  fluid-absorbent  board  of  peat  moss material  with  main  surfaces  having  different  fluid absorption rates.
