Title: Three-input floating point adder
Inventor: KAWAGUCHI TADAHARU
IPC: G06F7/76
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To simultaneously execute the simultaneous floating point addition of three operands and to execute a rounding processing by permitting zero with more than one bit to be between a rounding bit and a sticky bit. SOLUTION: When two operands are respectively digit-arranged to the other operand having a max. index part within the three, a digit arranging means 15 provides the bit for containing the carry of the sticky bits with the probability of occurrence at the time of addition so as to transmit a carry result. An adding means 25 inputs a digit arranging result, executes absolute value addition and transmits an addition intermediate result. Then, a normalizing means 30 inputs the addition intermediate result so as to normalize it and transmits the intermediate result where the logical sum of the whole low-order bits and sticky bits under the rounding bit adding the carry of the sticky bits is adopted as the new sticky bit.  Moreover, a rounding means 40 inputs the intermediate result, executes the rounding processing in accordance with a designated rounding mode and transmits an arithmetic result.

Title: Semiconductor integrated circuit device
Inventor: MASUDA KENZOU
IPC: G11C17/12
Filed: 1983-01-31
Abstract: PURPOSE:To obtain a semiconductor integrated circuit device containing a vertical ROM which is capable of a high-speed reading action by providing a precharge circuit which receives a precharge signal and supplies a precharge level to a well region. CONSTITUTION:A precharge MOSFETQp1 or Qpn is connected between each serial MOSFET and a positive power supply voltage OV. The Qp1 or Qpn is turned on while a timing signal phip is kept at a low level to precharge each juncture between an output line and the serial MOSFET up to a high level (OV). In other words, the output voltage of an inverter IV is set at a high level to set a well region WL1 at a high level. Therefore a parasitic diode consisting of the region WL1 and an n<+> region where the source and the drain of the serial MOSFET are formed is biased forward and turned on to transmit the above- mentioned high level to each source and drain. Thus the precharge is performed through said parasitic diode. This can extremely shorten the precharge time.
