Title: Synchronization of asynchronous data signals
IPC: H04J3/07
Filed: 1987-05-12
Abstract: In a synchronous network, asynchronous data signals are synchronized using positive/negative stuffing under the control of stuff request signals which are produced in dependence upon the phase difference between the asynchronous and synchronized data signals as compared to respective threshold values. The threshold values are cyclically changed in a manner to produce additional stuffing, not necessitated by the asynchronous frequency difference, whereby the frequency of jitter, due to stuffing, in the synchronized data signal is increased. The increased frequency jitter is filtered out in an already-provided phase locked loop

Title: Load/store with write-intent for write-back caches
IPC: G06F12/08
Filed: 1989-06-19
Abstract: A method for reading data blocks from main memory by central 
processing units in a multiprocessor system containing write-back 
caches. Load or gather instructions contain a write-intent flag. 
The status of the write-intent flag is determined. It is also 
determined whether a data block requested in the instruction by 
one of the processors is located in a corresponding cache, and if 
so, the requested data block is returned to the processor. If 
the data block is not in the cache and the write-intent flag 
indicates that the block will not be modified, the data block is 
read from main memory without obtaining a write privilege. The 
requested data block is subsequently returned from the cache to 
the processor. If the data block is not in the cache and the 
write-intent flag indicates the data block will be modified by 
the processor, then the data block is read from main memory while 
obtaining the write privilege. Subsequently, the requested data 
block is returned from the cache to the processor.

Title: Time division switch
IPC: H04L12/56
Filed: 1989-09-22
Abstract: The invention concerns Asynchronous Time Division Switches 
particularly for packet switching. In one embodiment a switch has 256 
ports running at 155 M bits and is capable of switching incoming data 
cells at each of the input ports to any one of 256 output ports. 
At each input port a switch sequentially distributes the received data 
cells over 16 outputs each of which is connected to a different DMR 
circuit. There are 256 DMR circuits each having 16 inputs and 16 
outputs. A DMR circuit is a fixed space switching device which has N 
inputs, N time intervals and N outputs and operates cyclically so that 
each input goes to each output for 1/Nth of the time. The inner 
stage of the ATD switch comprises 256 central switches each having 16 
inputs and 16 outputs. Each central stage switch has its 16 inputs 
connected to 16 different DMR circuits. The fourth stage of the 
switch consists of another array of 256 output DMR circuits with each 
central switch being connected to 16 different output DMR circuits. 
Each output DMR has its outputs connected to 16 different output 
ports. The internal circuitry of the ATD switch runs on 20 M bits. 
When a data cell is received at an input port its destination is 
derived from a header attached to the cell. Control circuitry enables 
the receiving port to request three address to query three possible 
routes through the switch. The ability to provide this series of 
questions is given by staggering the windows through which an output 
port can communicate with the central switches. Although data streams 
are received asynchronously the operation of the ATD switch is 
synchronous.  
     The switch is potentially capable of switching non ATD, synchronous 
traffic. Mixed mode of operation is possible.

IPC: H04L25/03
Filed: 1990-03-09
Abstract: An apparatus for scrambling/descrambling input data to 
produce output data. A data memory (32) stores a data word, a 
bit invert flag, and numerical data. A bit shift operating section 
(4) performs, on receiving a bit of data to be outputted or a bit of 
input data, a bit shift operation with the bit and stores the resultant 
data in the data memory (32) in the form of a first data word. A 
randomizing/derandomizing section (1) randomizes or derandomizes 
the input data by using the first data word and based on a 
generating polynomial and, depending on the state represented by 
the bit invert flag, inverts the bit of the data to be outputted to 
develop output data. A count processing section (2) increments or 
decrements the numerical value stored in the data memory (32) 
and, depending on the numerical value, selectively turns the bit 
invert flag to a predetermined state. A count controlling section 3 
replaces the numerical value with a predetermined initial value on the 
basis of the first data word and bit invert flag. The data memory 
(32) holds a second and a third data word (dw0, dw1), bits of 
which corresponding in position to a particular bit (B8, B9, B12) of 
the first data word are a ZERO and a ONE, respectively. The count 
controlling section (3) reads either one of the second and third data 
words (dw0, dw1) out of the data memory (32) depending on the 
value of the bit which is inputted to the bit shift operating section 
(4), Exclusive-ORs the data word (dw0, dw1), first data word, 
and third data word (dw1), performs a masking operation with a 
data word (a1) resultant from the Exclusive-ORing for validating a 
bit corresponding in position to the particular bit position (B8, B9, 
B12) of the first data word while invalidating the other bits, and 
replaces the numerical value with the initial value when a data word 
(a2) resulting from the masking operation is indicative of a ZERO or 
when the bit invert flag is in the predetermined state.

Title: Electronic keying of multi-board systems
IPC: G06F3/00
Filed: 1990-12-19
Abstract: A computer system with a number of subsystems or modules on separate circuit boards employs electronic keying to ensure proper configuration of these boards. A power key arrangement associated with a plug-in connector enables a separate power supply for each set of boards. A power supply turn-on signal is routed through a uniquely-configured connector path for each board, so the power supply turn-on is inhibited for improper configurations. The uniquely-configured connector path may use either a series or a parallel implementation. The series implementation employs a set of diodes connected for conduction in either of two directions, with the mating connector having its conductor paths connected to match the diode configuration; in this manner, the power supply enable signal can only flow through the series path if the proper board is plugged into a properly-coded slot, in which case the power supply to activate this board is activated through the series path including the diodes. The parallel implementation employs a given number of connector pins to establish the coding for each board, and each pin is either open-circuited or connected to ground; if this coding of the subsystem board is not the same as that of the slot into which it is plugged then the power supply activation signal will be shorted to ground by one or the other of the coded pins. <IMAGE>
