The bridge receives a command from a first bus, the command having an identification field and an address field. As the command is entered into a buffer in the bridge, the address field is checked against one or more addresses. If there is a match, then control bits are checked to see if the command will be allowed or not depending on the identification field value. If the command is not transferred to the second bus, a flag is set in the buffer, and an error message is returned to the first bus, and an interrupt may be generated. The control bits allow commands access to specific addresses on the second bus or deny the access depending on the command identification field. Bit-wise masking provides a range of values for identification and address field matching."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Processor bus bridge security feature for network processors or the like","description":"Described embodiments provide a system having a bridge for communicating information between two processor buses.
