摘要:
A system and method for analyzing large logic traces, with the system having an input for regular expressions, a generator for receiving the regular expressions and generating finite automata which use arithmetic/logic expressions that permit the use of a substantially infinite alphabet, an input for a large trace array, and an analyzer for searching the large trace array with the finite automata, with the analyzer producing results of the search.
摘要:
A circuit that may be implemented in a computer system that will measure the maximum and minimum time intervals for system elements to respond to a request for data or information. The circuit includes control logic that controls operation of the circuit, an up-counter and a down-counter that are used together for measuring the maximum or minimum response time interval, and a display for displaying the maximum or minimum response time interval that is measured during a test period.

A programming language type system includes, in a memory, a set of numeric type including integer types, fixed-point types and floating-point types, a set of type propagation rules to automatically determine result types of any combination of integer types, fixed-point types and floating-point types, constant annotations to explicitly specify a result type of a literal constant, context-sensitive constants whose type is determined from a context of a constant according to the set of type propagation rules, an assignment operator to explicitly specify a type of a value or computation, and operator annotations to explicitly specify a result type of a computation.
摘要:
A system and method for analyzing complex overlapping sequences of events in trace arrays, with the system having an input for receiving regular expressions that have been grouped in a predetermined manner, a generator for receiving the grouped regular expressions and generating multiple finite automata based on the groupings of regular expressions, with each finite automaton being generated using arithmetic/logic expressions to permit the use of a substantially infinite alphabet, an input for the trace array, and an analyzer for searching the trace array simultaneously with the multiple finite automata and providing a way by which the multiple finite automata may communicate with one another during searching, with the analyzer further outputting the results of the search.
摘要:
A high-speed pseudo-random number generator comprising a first shift register with p stages for storing and shifting a value with the least significant bit being adjacent an output terminal; a second shift register with b stages for storing and shifting a pre-loaded value with the least significant bit of the pre-loaded value being stored in the bth stage; a serial adder having at least l input taps with the serial adder adding the two values shifted out of the first and second shift registers and loading the sum output of the serial adder into the first shift register; and a controller for controlling clocking of the first and second shift registers and the serial adder, controlling pre-loading of the pre-load value into the second shift register, and clearing the serial adder.
