International Classification:

H04B 100

US Classification:

381119

Abstract:

A multimedia controller apparatus provides for computer programmed volume control and summing of audio signals in an enhanced multimedia environment. The apparatus is capable of receiving and processing inputs from a CD-ROM FM synthesizer, general MIDI audio, microphone, PCM sampled sound, and telephony systems. From these inputs, it produces outputs for PCM sampled sound, telephony systems, and stereo line-out. Additionally, it provides for the integration of telephonic support functions into a multimedia system. The multimedia controller apparatus comprises a volume control portion for receiving and controlling the volume of a plurality of analog input signals. The volume controlled input signals are then combined by an aggregation portion. A telephony processing portion is also provided for processing the telephony input signals. Stereo outputs, mono outputs, digital samplable outputs, and telephony outputs can be formed from the combined analog and telephony signals by an output portion.

International Classification:

H03K 513
H03K 5159

US Classification:

307603

Abstract:

A periodic sequence of signals is intiated and provided to a counter. During this time, a pulse (PULSE) is generated. Upon reaching a terminal count the pulse is terminated. The pulse is provided to a delay element which receives at its input a signal (s) entering, processed within or exiting a semiconductor device. The pulse and periodic sequence of signals are initiated by an edge detector detecting a trigger signal (TRIGGER), which may be the signal (s) being delayed. The sequence of signals is generated by a circuit element, such as a ring oscillator, and the periodicity of the sequence of signals is related to the inherent switching speed of the semiconductor device technology. A plurality of delay circuits are provided in a semiconductor device for individually delaying a plurality of signals entering, processed within and exiting the device. A library of delay circuits may pre-designed, and stored for implementation, as needed, in semiconductor devices.

Yen Chang - Saratoga CA

Assignee:

LSI Logic Corporation - Milpitas CA

International Classification:

G06F 922

US Classification:

395375

Abstract:

A general purpose architecture for a digital microcomputer, which includes a central processing unit, random access memory, user-defined dedicated functions and an optional programmable read only memory. Instructions are fetched either externally or from the optionally ROM. Data can be fetched externally or internally. Each instruction fetched is interpreted by a general-purpose microengine. The architecture is flexible enough to permit the modular addition, deletion and modification of dedicated functions and microinstructions (including changes in execution timing and decoding), as well as the testing of memory independently from the rest of the architecture.

International Classification:

G06F 750

US Classification:

364786

Abstract:

An adder array for adding two or more input addends, whose bit lengths are not necessarily matched, and a method of configuring the adder array are disclosed. The addends are organized according to bit weight, and bits of equal weight are added in adder columns. Carry-outs are introduced into subsequent, higher weight adder columns according to delay. Thereby, the delay associated with the addition of the addends is minimized. Method and apparatus is disclosed.

H05K 7/14

Abstract:

A system compatible for use with ATCA includes a chassis comprising a first and a second plurality of slots for receiving circuit boards. The chassis further includes a midplane having a front surface and a back surface. The midplane extends between the first plurality of slots and the second plurality of slots. The midplane has a first plurality of connectors affixed to the front surface and has a second plurality of connectors affixed to the back surface. Each connector is arranged to accept a circuit board. The midplane forms an interconnection scheme such that one of the first plurality of slots is directly connected to one of the second plurality of slots. The one of the first plurality of slots and the one of the second plurality of slots extend in opposite directions from their respective connections on the midplane.
