摘要:
An information processing device for sequentially reading and executing programs stored in memory means, including: a program counter for outputting an address for reading a program to the memory means; an instruction decoder for decoding instructions read from the memory means in response to a control signal indicating a period in which the types of codes used in at least a field among fields constituting an instruction in the program are limited to a predetermined number or less; and controlled means for performing processing corresponding to the decoded results output from the instruction decoder. The instruction decoder has a reconfigurable circuit for changing the circuit configuration in response to the control signal so that the decoding is performed based on a relationship between codes in a field in which the types of codes used are limited and decoded results, the relationship being set so that the number of times of change of bit values in the field is reduced.

摘要:
A terminal device transmits device information thereof and a request for acquiring information contents to a contents distribution device. The contents distribution device generates a request for distributing a program for materializing the information contents in the terminal device based on the information contents designated in the acquisition request and the device information, and transmits a license request for using a function standard required for realizing the function to a license management device. The license management device receives the usage license request and correspondingly transmits an authorization for using the function standard to the program distribution device and the contents distribution device. The program distribution device transmits the program to the terminal device only when the usage authorization is received. The contents distribution device transmits the information contents to the terminal device only when the usage authorization is received.

A terminal device transmits device information thereof and a request for acquiring information contents to a contents distribution device. The contents distribution device generates a request for distributing a program for materializing the information contents in the terminal device based on the information contents designated in the acquisition request and the device information, and transmits the distribution request to a program distribution device and transmits the device information to an inspection device. The program distribution device transmits the program in the distribution request to the inspection device. The inspection device inspects a materialization state of the information contents in the terminal device based on the program and the device information and transmits a result of the inspection to the program distribution device and the contents distribution device. The program distribution device transmits the program to the terminal device and the contents distribution device transmits the information contents to the terminal device only when the inspection result is favorable.
摘要:
A semiconductor integrated circuit including a digital circuit and an analog circuit which are integrated on a single semiconductor chip comprises a first electrostatic destruction protection circuit, connected to a digital circuit, for protecting the digital circuit from destruction caused by ESD therein by an influence of an input digital signal and a second electrostatic destruction protection circuit, connected to an analog circuit, for protecting the analog circuit from destruction caused by ESD therein by an influence of an input analog signal. A first grounding conductor connected to the first electrostatic destruction protection circuit and a second grounding conductor connected to the second electrostatic destruction protection circuit are connected to each other outside the semiconductor integrated circuit.

A digital signal processor capable of performing a Viterbi algorithm is provided. The digital signal processor includes an instruction fetching unit that fetches instructions; a decoding unit that decodes the instructions fetched by the instruction fetching unit, and an execution unit that executes the instructions decoded by the decoding unit. The execution unit includes a first comparing unit that compares first data with second data and a second comparing unit that compares third data with fourth data. The first comparing unit and the second comparing unit operate in parallel. Also, the first data, the second data, the third data, and the fourth data can each be one of four results obtained by adding one of two path metrics to one of two branch metrics. The execution unit outputs any two new path metrics in a high order position and a low order position respectively.
