Patent number: 8392644Abstract: A processing system is provided consisting of an interrupt pin, multiple registers, a stack pointer, and an automatic interrupt system. The multiple registers store a number of processor states values. When the system detects an interrupt on the interrupt pin the system prepares to enter an exception mode where the automatic interrupt system causes an interrupt vector to be fetched, the stack pointer to be updated, and the processor state values to be read in parallel from the registers and stored in memory locations based on the updated stack pointer, prior to the execution of an interrupt service routine. A method for automatic hardware interrupt handling is also presented.Type: GrantFiled: July 30, 2010Date of Patent: March 5, 2013Assignee: MIPS Technologies, Inc.Inventors: Erik K.

Patent number: 7523088Abstract: A transactional database server is accessible by applications. Applications indicate whether access is made using an online protocol. Where the database server determines that a request received from an application is made using the online protocol, the server will return one of a set of defined error codes upon identified system resources being determined to be scarce. Applications monitor responses from the database server for the defined error codes. On receipt of one of the defined error codes an application will issue a commit to the database server to attempt to release system resources for use by applications.Type: GrantFiled: March 31, 2004Date of Patent: April 21, 2009Assignee: International Business Machines CorporationInventors: Leo Tat Man Lau, Marko Milek, Adil M.
