摘要： A control mechanism for data bus communications employs channels to which bus transactions are assigned, each channel having independent flow control. The control mechanism enforces an ordering algorithm among channels, whereby at least some transactions may pass other transactions. Channel attributes are programmable to vary the ordering conditions. Preferably, each channel is allocated its own programmable buffer area. The control mechanism independently determines, for each channel, whether buffer space is available and enforces flow control independently for each channel accordingly. Flow control is preferably credit-based, credits representing buffer space or some other capacity of a receiver to receive data. Preferably, the flow control mechanism comprises a central interconnect module controlling internal communications of an integrated circuit chip.

摘要： A communications bus for a digital device includes a credit-based flow control mechanism, in which a sending component maintains a local record of its credits. Credits are returned to the sender by pulsing a single-bit credit return line. A separate mechanism provides a count of available credits from the receiver, the separate mechanism not necessarily being current. The local record is compared to the count of credits from the separate mechanism over a pre-determined time interval, failure of the two values to agree at any time during the interval indicating a probable credit discrepancy. A credit discrepancy is confirmed, preferably by suspending certain bus activity for a sufficiently long period to account for any delay in propagating credit value changes, and re-comparing the values. Preferably, the bus communicates between internal components of an integrated circuit chip.

摘要： An integrated circuit chip includes multiple functional components and a central interconnect (CI) module. Each functional component communicates with the CI module via a respective internal bus sharing a common architecture which does not dictate any particular data alignment. The chip architecture defines an alignment mechanism within the CI module, which performs any required alignment of transmitted data. Alignment mechanism design parameters can be varied to accommodate different alignment domains of different functional components. Preferably, the common bus architecture supports multiple internal bus widths, the CI module performing any required bus width conversion. Preferably, for certain transactions not containing a data address, correct alignment is obtained by placing restrictions on transaction size and boundaries, and duplicating certain data on different alignment boundaries. The use of a common bus protocol and CI module having alignment capability streamlines the design process and reduces the overhead of alignment conversion.

摘要： A computer processor floating point processor six cycle pipeline system where instruction text is fetched prior to the first cycle and decoded during the first cycle for the fetched particular instruction and the base (B) and index (X) register values are read for use in address generation. RXE Instructions are of the RX-type but extended by placing the extension of the operation code beyond the first four bytes of the instruction format and to assign the operation codes in such a way that the machine may determine the exact format from the first 8 bits of the operation code alone. ESA/390 instructions SS, RR; RX; S; RRE; RI; and the new RXE instructions have a format which can be used for fixed point processing as well as floating point processing where instructions of the RXE format have their R1, X2, B2, and D2 fields in the identical positions in said instruction register as in the RX format to enable the processor to determine from the first 8 bits of the operation code alone that an instruction being decoded is an RXE format instruction and the register indexed extensions of the RXE format instruction, after which it gates the correct information to said X-B-D adder. During the second cycle the address add of B+X+Displacement is performed and sent to the cache processor's, and during the third and fourth cycles the cache is respectively accessed and data is returned, and during a fifth cycle execution of the fetched instruction occurs with the result putaway in a sixth cycle.

摘要： A pipelined computer processor in a milli-mode architected state tests the validity of a program status word with a mask stored in a millicode general register. The mask indicates bits in the program status word which are to be zeros if the word is valid. A logical AND operation is performed between correspondingly positioned bits in the word and bits in the mask and in addition the status of at least one other bit in the word is checked, a bit other than a correspondingly positioned bit.

摘要： A computer processor that uses an AAHT to provide a guess at the real (absolute) address bits used to access the cache and directories that is more accurate in a high-frequency design which prevents any sort of full or large partial adds of ranges of base, index, or displacement has two index values generated and two AAHT arrays, one each for instruction and operand logical requests. It handles cases in which the data is not directly from the GPR array. For designs that aim at improving performance data for some operations that update GPR's may be used for address generation prior to the execution and write to the GPR array, these include data bypass for Load Address (LA) and Load (L). The system handles instruction fetches, relative branches, other special instruction address instruction fetch requests, and those started as a result of a branch history table (BHT) predicted instruction fetch. A method for AAHT synonym resolution improves the accuracy of the index value for an Absolute Address History Table buffer.
