    摘要: A high performance integrated circuit (IC) with independent read and write data busses enables full simultaneous read and write data transfers between devices coupled to the buses. Multiple master and multiple slave devices communicate using the resources of a bus controller and a bus arbiter. Having separate read and write data busses with separate and independent arbitration allows reads and writes from different devices to occur simultaneously. Many high performance IC, like systems on a chip (SOC), have many different functional units communicating with a central processing unit (CPU). Many such CPUs have architectures that may cause in certain applications an unbalance between read and write traffic on the independent busses. Master and slave devices contain auxiliary internal read and write data buses multiplexed such that read or write data may be interchanged. A corresponding Auxiliary_(read or write) command is routed to the slave units to notify the units when to route normal read or write data to an idle bus. The bus controller may use this added feature to optimize the available bandwidth of independent read and write data busses up to the limit where a read or write bandwidth may be two times that available if the read and write data buses were used only for their normal traffic.

    摘要: Embodiments comprise an adjusted polysilicon gate pitch to metal wire pitch relationship to improve area scalars while increasing ACLV tolerance with a fixed polysilicon gate pitch. In some embodiments, the wire pitch for at least one metallization layer is adjusted to match the pitch for the polysilicon gate. In one embodiment, the next to the lowest metallization layer running in the same orientation as the polysilicon gate, utilized to access the input or output of the interconnected cell structures is relaxed to match the minimum contacted gate pitch and the metal is aligned above each polysilicon gate. In another embodiment, the polysilicon gate pitch may be relaxed to attain a smaller lowest common multiple with the wire pitch for an integrated circuit to reduce the minimum step off.

    摘要: A precise and programmable duty cycle generator which can produce a user definable duty cycle clock signal with precision. This circuit is comprised of a number of generally known circuit elements such as a digital to analog converter (DAC), low pass filter (LPF) and operational transconductance amplifier (OTA), as well as a unique voltage controlled duty cycle generator (VCDCG). The circuit has the ability to produce a user programmable duty cycle clock signal with precision over a broad range of operational frequencies. The VCDCG circuit is unique and employs a number of stages, each of which has a current starved inverter which is immediately followed by a conventional inverter to allow duty cycle corrections to be either additive or subtractive. The current starved inverters are controlled by a single voltage, which causes the current starved inverter's delay to degrade/improve on only one transition to effect a change in the duty cycle. For improved precision, a differential embodiment employs the same VCDCG.

    摘要: The present invention provides a method and system for bypassing defective sections with a memory array of a computer chip. The circuit in accordance with the present invention includes a register for controlling the effective size of the memory array based upon the detection of at least one defective section in the memory array, and a multiplexer for receiving an index address for the memory array and for the mapping of the index address based upon the register means. The circuit in accordance with the present invention does not use fuses to conduct repairs and thus does not require additional area on the chip for such fuses. As such, it eliminates the complications in the manufacturing process related to fuses and redundant cells. The circuit in accordance with the present invention dynamically manipulates the address of the array to bypass the defective regions of the array. Although the present invention results in a reduction in the overall size of the array, and thus may result in performance degradation, it allows for the continued operation of the chip. For an embedded memory, the chip need not be discarded. Importantly, unlike the conventional method, the circuit in accordance with the present invention has the ability to handle defects which are introduced during usage, and defect detection and bypass are initiated each time the computer is initialized. Thus, the circuit in accordance with the present invention has utility subsequent to manufacturing testing. A chip with embedded memory which has the steering circuit of the present invention is thus more reliable than memory chips repaired with conventional methods.

    摘要: A small and efficient control circuit for a compensated CMOS off-chip driver and a driver circuit incorporating the control circuit. The control circuit uses an exclusive OR gate as a phase detector to determine the phase difference between a system clock and a delayed version of the system clock. An RC filter smooths the output of the exclusive OR gate to produce a voltage proportional to the delay introduced in the CMOS circuitry by environmental and process variables. The voltage from the RC filter is used as a control voltage to control the effective channel width of the effective pull-down device of the off-chip driver circuit. An off-chip driver using the control circuit is used in the I/O unit of a CMOS integrated circuit chip.
