Abstract: A system for dynamically allocating buffers between components in a computer system is described. The system uses matched sets of bi-directional buffers to control data flow between the processor and the computer bus. The dynamic buffer allocation system allows simultaneous data transfer from the processor to the buffers, and from the buffers to the computer bus.

Abstract: An apparatus, system and method permitting dynamic configuration of I/O device adapters connected to a bus utilizes a function configuration register to store a READY/NOT READY status for each of the I/O device adapters. Upon the occurrence of a reset condition, dynamic configuration decision logic detects which I/O device adapters are connected to the bus, determines configuration parameters for each connected I/O device adapter, initializes the configuration space for each connected I/O device adapter, and then sets a corresponding flag in the function configuration register to indicate ready status. An I/O device driver interrupts a configuration process to examine the function configuration register. If ready status can be confirmed from this function configuration register within a time out period, then the configuration process may proceed; otherwise, a device error recovery process is initiated.

Abstract: A data compression device includes a data compression circuit for compressing data being transferred between a TV game player and a memory card, and for decompressing data sent from the memory card to the game player. The device is arranged to be inserted into the card receptacle of the TV game player, and includes an opening for receiving the memory card, thereby serving as an adapter between the game player and the memory card.
