Title: Multiplexing information from different data rate channels
Inventor: TURUDIC ANDY
IPC: H04J3/16
Filed: 1991-07-17
Abstract: A data transmission method provides for transmitting lower data rate information in a higher data transmission rate environment with information entities to be transmitted broken into smaller (e.g. 2 bit) entities called nyblets. For channels operating at a maximum transmission rate nyblets are clocked from memory at a rate that allows the nyblets to be serially assembled into expected bit length words. For channels operating at less than the maximum transmission rate, where in conventional systems information was transmitted redundantly to achieve compatibility with higher data rate systems, information is now transmitted without duplication as a plurality of nyblets in series until the expected bit length is achieved. The result is that more information can be transmitted over a communication medium, since duplicate or redundant transmission of lower data rate information is avoided. The method is used for ISDN-D channels allowing 16K bits per second to be transmitted in a 64K bits per second environment. <IMAGE>

Title: Computation of sticky-bit in parallel with multiplication
Inventor: PALANISWAMI KRISHNAN J
IPC: G06F7/52
Filed: 1993-03-22
Abstract: A floating point unit multiply logic in which a sticky bit is computed in parallel with partial product generation and reduction for three different rounding precisions and two different operand ranges. Two sticky bits need to be calculated during the parallel operation because the result can be anywhere between 0 and 4 and it will not be known which is correct until after the result of the multiplication has been calculated. If the result is between 0 and 2, then a first sticky bit is generated. When the result is between 2 and 4, a second sticky bit is generated. It is not known which sticky bit is the correct one to use until the final addition is performed. Once the results of the final addition is known, the correct sticky bit is selected using a carry out from the adder, the overflow bit. <IMAGE>
