摘要： A computer system has a memory and has a processor coupled to the memory, the processor having an access control arrangement for delaying completion of a memory access until the occurrence of a control signal. A deterministic circuit coupled to the-processor and the memory has a register arrangement containing control information loaded by the processor, the deterministic circuit having a signal generation arrangement for generating the control signal. The signal generating arrangement includes a selective delay arrangement which can selectively delay generation of the control signal during an access to the memory by a time interval having a duration which is a function of the control information in the register arrangement.

摘要： A communications system for the delivery of digital data programs to a remote location includes a transmitter for transmitting a signal having the digital data programs and a communications terminal located at the remote location. The communications terminal includes a control circuit including authorizing circuitry responsive to authorization data for authorizing the communications terminal to access authorized ones of the digital data programs in one of a first and a second authorization mode. For example, automatic authorization modes for game play may comprise an arcade mode and a rental mode, simulating manual access methods i.e. paying for play at a video arcade or for rental of games from a video game store. Moreover, new games may be accessed without charge by the game player if authorized according to a free service authorization map. Furthermore, parents may limits game play to children prior to a particular time of day such as bed-time or to a maximum playtime limit according to a secret downloadbale password known only to the parents. A game player may only read and not write authorization and control data.
