Assignee:

TRW Inc. - Redondo Beach CA

International Classification:

H03K 1712

US Classification:

361 93

Abstract:

A current limiting circuit and technique is provided for preventing excessive current supplied to a circuit and for providing self-recovery characteristics thereto. The current limiting circuit includes an input for receiving a supply voltage for supplying power to the monitored circuit and an output for providing the power to the desired circuit being monitored. The circuit employs a drive transistor having a source connected to the input and a drain connected to the output. The drive transistor further includes a gate for receiving a control signal. A current mirror circuit is provided for sensing a current overload and adjusting the control signal to indicate the amount of current drawn. During normal current draw, the circuit provides the supply voltage as the output. When excessive current draw is detected, the drive transistor is turned off and the output current is thereby cut off.

International Classification:

G06F 1202

US Classification:

395413

Abstract:

A virtual addressing buffer circuit has improved address mapping and control flexibility for improved physical resource management and a unique opportunity for forward-compatible system design. The virtual addressing buffer formats the output address utilizing a format register as a combination of the new address bits and the original input address bits. The ability to format the output address enables the user to replace certain address bits without requiring that the entire address be replaced. The virtual addressing buffer controls the output of several command signals to external circuits to indicate how the system should respond to the address output from the virtual addressing buffer. The command signals are controlled by a command register and are output from the virtual addressing buffer only when an address match has been verified. The virtual addressing buffer circuit filters out certain bits of an input address as indicated by a filter register before it verifies that the input address matches a stored address.

International Classification:

G06F 1200

US Classification:

711167

Abstract:

A rule-based DRAM controller asserts memory access and control signals (including the CAS, RAS, WE, and address data signals) based upon pre-specified control rules. Certain pre-specified rules, or conditions, are used by the DRAM controller to determine the timing and sequence of the memory accessing and control signals output by the DRAM controller. The control rules for asserting the various memory accessing signals are advantageously implemented as logic within the DRAM controller, while the conditions and qualification for the control rules are provided from various monitoring signals and independently operating timing modules which keep track of the DRAM and controller states. Based upon these rules and conditions, the request inputs to the DRAM controller are interpreted to provide optimum access speed to the DRAM.

International Classification:

G06F 9455

US Classification:

711202

Abstract:

A method and apparatus using a virtual addressing buffer circuit afford address mapping and control flexibility to provide a unique opportunity for device emulation and software debugging. The method permits the emulation of a device which is physically not present in a CPU controlled system utilizing a virtual addressing buffer circuit. The method includes the step of storing a match address which corresponds to an address location of the device. The virtual addressing buffer intercepts an address request from a CPU for the address location of the device. Bits of the requested address which are not relevant to a determination of whether the requested address matches the match address are filtered out to produce a filtered request address. The filtered request address is compared with the match address, and a match indicator is activated when the filtered requested address matches the match address. A terminate command is provided to a bus controller connected to the CPU and a local memory when the match indicator is active.

Inventors:

Jason S. Kim - Los Angeles CA

Assignee:

AST Research, Inc. - Irvine CA

International Classification:

G09G 300

US Classification:

241 20

Abstract:

An electronic keyboard template for use with software applications programs is responsive to command signals transmitted by designated function keys on a computer keyboard. The template includes an LCD display screen for displaying icons representative of operations performed by the function keys, control circuitry, and driving circuitry for generating the display of the icons on the LCD screen. In a preferred embodiment, the control circuitry includes a microprocesor, a Random-Access-Memory, and a digital Look-Up-Table, and the driving circuitry comprises a matrix driver and a refresh sequencer. The driving circuitry may further include a DC-to-DC convertor, and a plurality of shift registers for energizing pixel locations designated within a grid system on the LCD screen. In an alternative embodiment, the control circuitry may be external to the template (e. g. , within the keyboard).
