Patent EP-0349085-A3 (EP)
IPC: C08F2/00
Filed: 1989-06-27
Abstract: A process for incorporating carboxyl and/or 
carboxyl derivative functionality into a hydrocarbon 
polymer which is substantially free of ethylenic 
unsaturation. The functionalization is accomplished by 
contacting the functionalizing agent or agents with the 
polymer in the presence of a free radical initiator in 
a blending apparatus capable of imparting high 
mechanical energy into the reaction medium. The 
blending apparatus is preferably an extruder and most 
preferably a non-intermeshing twin screw extruder. The 
amount of degradation resulting from the presence of a 
free radical initiator and the high mechanical shear at 
the elevated temperatures employed during the contact­
ing is reduced by effecting the contacting in a suit­
able diluent. Similarly, the amount of polymer cross­
linking and/or coupling is reduced through the use of a 
suitable diluent. The polymer is maintained in the 
molten phase during the reaction.

Title: Noise shaping requantization circuit
IPC: H03H17/00
Filed: 1990-06-05
Abstract: In a noise shaping requantization circuit, a 
requantized output digital signal Y(z) and an input 
digital signal X(z) are processed in an operational 
circuit (3) whose output signal (A(z) is requantized to 
provide the requantized output signal. The processing 
circuit can be configured in a variety of ways but has 
fixed limitations established for circuit parameters 
which determine the relationship beween the output 
signal therefrom and the two input signals. By 
comparison with prior art noise shaping requantization 
circuits, a substantially better S/N ratio (assuming 
equal values of output signal resolution), or a substan­
tially lower degree of output signal resolution 
(assuming equal values of S/N ratio) can be achieved, 
with stable operation.

Title: Clipping circuit
IPC: H03G11/00
Filed: 1990-05-18
Abstract: The clipping circuit has a voltage reference (3) and a transconductance (5) connected to a voltage input (Vin). The input is connected through the transconductance (5) to an output resistor (Rout). The voltage output is taken between the output resistor and the transconductance (5). The voltage reference (3) has a third current source (I3) feeding a diode connected transistor (Q1) and a resistor (R1). A second current source (I2) feeds into the resistor after the transistor. The base of the diode connected transistor (Q1) is connected to the voltage input. The transconductance (5) has a second transistor (Q2) whose base is connected to the voltage input, collector sinks current from a fourth current source and emitter feeds current to a resistor (R2). A first current source (I1) feeds. current to a third transistor (Q3) and to a current mirror. The base of the third transistor (Q3) is connected between the fourth current source (I4) and the collector of the second transistor (Q2). The current mirror draws current from the output resistor (Rout) and feeds current to between the emitter of the second transistor (Q2) and its associated resistor (R2). The transconductance creates a feed back loop such that a change in the first and second current sources creates a steady-state current drawn through the resistor (R2) that is one-half of the first current source current. The circuit produces symmetrical clipping of an input voltage signal at the voltage output.

Title: Conversion of internal processor register commands to i/o space address
IPC: G06F9/30
Filed: 1991-06-27
Abstract: 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.
