摘要:
A device that includes an electronic device referred to as an integrated circuit interposer is disclosed. The integrated circuit includes a voltage regulator module. The interposer is attached to an electronic device, such as another integrated circuit, and facilitates control and distribution of power to the electronic device. The integrated circuit interposer can also conduct signaling between the attached electronic device and another electronic device. The voltage regulator module at the integrated circuit interposer can be configured to provide a voltage reference signal to the attached electronic device. Generation of the voltage reference signal by the integrated circuit interposer can be enabled or disabled and the value of the voltage reference signal can be adjusted, depending on operating requirements of the electronic device.

A method of generating a clock signal using a digital frequency synthesizer includes providing a base clock to the digital frequency synthesizer, comparing a phase of an output clock from the digital frequency synthesizer with a phase of a reference signal, and issuing at least one frequency control command to the digital frequency synthesizer to align the phases.

A system and method can mitigate voltage fluctuations. According to one embodiment, a delay system provides a delayed version of a first reference signal as a function of a supply voltage. A comparator provides a control signal for controlling a protection device based on the delayed version of the first reference signal and a second reference signal. The amount of delay provided by the delay system defines a threshold based on which the comparator provides the control signal.

A method of operating a static random access memory (SRAM) having a column clear function by performing write operations using a two step process. To perform a write, each cell in a row to be written is preset during a first step. Then, each cell that is to have a zero written to it is cleared using a column clear operation. A column of cells may be cleared by enabling all the rows for clearing, then asserting column clear control signals for each of the columns in the array to be cleared. A subset of columns of a plurality of rows may be cleared by asserting a plurality of column clear signals corresponding to the subset of columns and a plurality of work lines corresponding to the plurality of rows.

The present invention includes a system for and a method of determining noise characteristics of a circuit of an integrated circuit. The circuit is classified based on its topology and measured circuit parameters. Noise characteristics are retrieved using the circuit classification and circuit parameters to calculate a noise response. Classification and characterization may be performed on each individual input.

Scan chain links which step data through a scan chain using only a single control signal, and which require a reduced number of transistors to scan data into and out of a latch. One scan chain link, which allows the output of a scanned latch to “wiggle”, uses eight transistors and only a single control signal. Another scan chain link, which prevents the output of a scanned latch from “wiggling”, and which allows data to be maintained in a latch during a scan operation if it is so desired, uses twenty-five transistors and two control signals: one control signal for stepping data through a scan chain, and an additional control signal for preventing the output of a scanned latch from wiggling.
摘要:
An SRAM that has a column clear function with only three vertical lines and six total lines across a cell and a method of operating that cell and an array of those cells. Instead of two bit lines per port and two access devices per port as in a traditional SRAM cell, one bit line and one access device per port is used. In addition, one additional bit line, one additional word line, and two devices in series are used to perform the column clear operation and complete a write operation. The cell is operated by performing write operations using a two step process. To perform a write, each cell in a row to be written is preset during a first step. Then, each cell that is to have a zero written to it is cleared using the additional bit line and additional word line to address the cells to be cleared. A column of cells may be cleared by enabling all the rows for clearing, then asserting column clear control signals for each of the columns in the array to be cleared.
摘要:
A fully 2's complement FMAC (floating-point multiply accumulate unit) produces an unrounded output. The unrounded output is associated with a single INC bit, and is provided for early delivery as an FMAC operand. The INC bit is set using rounding logic which anticipates how a 2's complement conversion will affect a number, and then sets the INC bit in response to a rounding mode, and current L, G, S and sign bits. The rounding logic is configured to implement a truth table which demonstrates that rounding and 2's complement incrementation are mutually exclusive. When a bypassed result is received as an input to an FMAC, a delayed incrementer merges the unrounded C operand with its INC bit. The C incrementer and additional 2's complement conversion logic are placed approximately parallel with the multiply unit so that no additional delay is incurred in the FMAC's critical path. An INC bit corresponding to an A or B operand is absorbed within the FMAC's multiply unit. The FMAC allows an entire adder to be eliminated since the (A*B) result and C operand may be added in a single 2's complement adder rather than two carry propagate adders coupled to an end-around carry MUX.
