  • System for interfacing ISA compatible computer devices with non-ISA buses using secondary DMA controllers and glue logic circuit
    Patent number: 5954802
    Abstract: A system and method that allows ISA-compatible DMA devices (60) to communicate over non-ISA buses such as the VL bus (20) and a PCI bus (30). In a computer system (10) with a non-ISA bus, the present invention couples a secondary set of DMA controllers (50) in the same input/output space and a glue logic circuit (70) to the non-ISA bus in the computer system (10) to allow the ISA-compatible DMA device (60) to operate over the non-ISA bus. The secondary set of DMA controllers (50) provides the support for an ISA-compatible DMA device (60) to perform DMA transactions and the glue logic circuit (70) directs the DMA controller accesses to the proper place in the computer system (10).

  • System for blocking access to a computer device using a glue logic circuit operable to force a target computer device to perform a target abort
    Patent number: 5935223
    Abstract: A system and method that blocks access to a computer device, for example a direct memory access controllerdevice (50), coupled to a PCI bus (30). In a computer system (10) with a PCI bus (30), the present invention couples a glue logic circuit (70) to the PCI bus (30) to block access to the target computer device. The glue logic circuit (70) can also allow access to a requested computer device. In another aspect, the present invention couples a control module (170) to the PCI bus (30) to block access to the target computer device.
