摘要:
A computer apparatus incorporating special instructions to force load and store operations to execute in program order. The present invention provides a new and novel store instruction that is suspended until all prior store instructions have been completed by an associated CPU. Also, a new load instruction is provided which blocks any subsequent load instructions from executing until this load instruction has been completed by an associated CPU. These instructions allow for high efficiency computer systems to be implemented which optimize instruction throughput by executing subsequent instructions while waiting for a prior instruction to complete.
摘要:
A method and apparatus (1203, 1403) for embedding identification information in documents. The present invention embeds information in each copy of a document (1207, 1407) such that a particular copy of the document is distinguishable from all other copies of the same document. Additionally, this embedded information (1209, 1301, 1409) is designed to remain intact even if the original is copied. A method and apparatus is also disclosed to embed verification information in a printed document (1207, 1407) such that modification to the text subsequent to printing is detectable.

摘要:
A method for operating a digital computer in response to the occurrence of an exception is disclosed. The method provides for the examination both of the contents of a predetermined computer location and of the instruction code for the instruction causing the exception. The computer then utilizes the results of those examinations to determine the dismissibility of the exception. The computer transfers control to the next instruction after the instruction which caused the exception if that instruction is dismissible.
