摘要： A system and method for distributed cache. Cache tag storage and cache data storage are maintained in separate pipeline stages. Cache tag storage is operated by a data producer. Cache data storage is operated by a data consumer. Cache hits and misses are determined by the data producer prior to any operations being performed by the processor. In the event of a cache miss, produced data is sent to the processor to be processed. In the event of a cache hit, the cache address of the corresponding previously processed data is sent to the data consumer so that the corresponding processed data unit can be retrieved from cache data storage.

摘要： A data transfer device for coupling a processor to a system bus. The data transfer device includes data packers and unpackers for converting between data blocks of a first size and data blocks of a second size, e.g. between bytes or words and longwords. The data transfer device also includes an internal buffer memory system for storing the data being transferred. The processor and system bus are selectively coupled, each one at a time, via a direct data path, to the internal buffer memory system permitting both the processor and the system bus to independently read and write data, each at their normal data transfer rate.

摘要： A method for generating an address for addressable locations of a computer system where two registers are overlapped. Those bits of the two registers that overlap are logically combined together using a boolean operation when generating the address. Using this method, the higher order register can be used to select a segment of the addressable space of the computer system. Then, all accesses to that portion of the addressable space can be controlled by changing only the lower order register. This results in a saving of time since only one of the registers need be reloaded for each subsequent access.

摘要： A memory device comprising memory cells having volatile and non-volatile memory portions. The volatile memory portion of each cell includes circuitry for performing RAM functions while the non-volatile memory portion comprises circuitry defining pre-coded data. The memory device comprises a mechanism to operate an initialization sequence, which sets the initial state of the volatile memory portion of each memory cell to the pre-coded data defined in the associated non-volatile memory portion. The initialization sequence allows the initial state of each memory cell's volatile portion to be re-established after power has been applied to the memory device.

摘要： An access request prioritization and summary device for determining the current highest priority among n entities. The device includes a bitmap having n bit storage locations. Each one of the n bit storage locations corresponds to one of the entities and is used to store a value which represents when the corresponding entity is available for prioritization. A plurality of combinational logic blocks are connected to the bitmap so that each one of the combinational logic blocks receives a preselected portion of the values stored in the n bit storage locations of the bitmap. Each one of the combinational logic blocks has a token signal input and a token signal output. The token signal inputs and outputs are coupled together to form a series of token signal links between the combinational logic blocks. When certain preselected highest priority determination conditions occur within one of the combinational logic blocks, the combinational logic block generates a token signal which serves as the token signal to the respective succeeding combinational logic block. Each combinational logic block is capable of receiving a token signal from the previous combinational logic block and is responsive to the input of a token signal to determine a current highest priority from the values which it received as input signals.

摘要： An apparatus and method for supplying an address and data to an external memory device. The number of pins available for supplying the address is less than the number of address lines required at the external memory device. A register is used to store the high order bits of the address and is pre-loaded with a default page value. An output of the register is coupled to an address input of the external memory. If the high order bits of the address are equal to the default page value, a control device couples the data lines directly to the external memory device and a read or write operation follows. If the two values are different, a paging cycle is performed where the high order address bits are latched through the register to the address input of the external memory and then the data bits are coupled to the external memory device. If the default page value points to the most accessed portion of the external memory device, no paging is performed during access to that portion of the external memory and processing time is saved when reads or writes of data are made to that portion of the external memory.

摘要： A queue based arbiter to arbitrate between N devices of a computer system for access to a system bus which eliminates the need to maintain a history of bus transactions by queuing bus requests to track when a bus request is posted. The arbiter provides fair access to the bus by maintaining a queue of requests that come in from each resource in the computer system. This is accomplished by continually sampling the individual request lines of the devices to determine if a device is requesting access to the bus. Each time the arbiter detects a request from a device it puts an entry representative of the specific device that has requested the bus into a queue that has at least N entries. Requests are granted in the order that they are queued.
