Filed:

Apr 13, 2001

Appl. No.:

09/833578

Inventors:

Joel Zvi Apisdorf - Reston VA, US
Sam Brandon Sandbote - Reston VA, US
Michael Daniel Poole - Reston VA, US

Assignee:

The United States of America as represented by the Secretary of the Navy - Washington DC

International Classification:

G06F013/00

US Classification:

712235, 712 22

Abstract:

A system and method forward data between processing elements. A first processing element includes an address register that stores a first memory address. A forwarding storage element is coupled to the first processing element. A second processing element, coupled to the forwarding storage element, transmits a second memory address to the forwarding storage element. The forwarding storage transmits the second memory address to the first processing element, and the first processing element compares the second memory address with the first memory address.

Assignee:

The United States of America as represented by the Secretary of the Navy - Washington DC

International Classification:

G06F009/46

US Classification:

718100, 718102

Abstract:

A system and method process data elements on multiple processing elements. A first processing element processes a task. A second processing element, coupled to the first processing element, is associated with a task. The first processing element sends a critical-section end signal to the second processing element while processing the task at the first processing element. The second processing element resumes the task in response to receiving the critical-section end signal.

Appl. No.:

09/933786

Inventors:

Sam B. Sandbote - Reston VA, US

Assignee:

The United States of America as represented by the Secretary of the Navy - Washington DC

International Classification:

G06F 9/315

US Classification:

712300, 712224

Abstract:

An apparatus for shifting data is disclosed. The apparatus includes a shifter, a register, and a shift post processor. The shifter shifts an operand according to an offset parameter, thereby generating a shifted operand. The register is coupled to the shift post processor to transfer a shift carry operand stored in the register to the shift post processor, and coupled to the shifter to store the shifted operand after any transfer of the shift carry operand. The shift post processor is coupled to the shifter and the register to process the shifted operand to generate an output based on at least a control signal and a mask field. The shift post processor comprises a decoder to decode the offset parameter into the mask field, the mask field having a plurality of mask bits, each of the mask bits corresponding to a bit position of the shifted operand.

Assignee:

The United States of America as represented by the Secretary of the Navy - Washington DC

International Classification:

G06F 3/00
G06F 15/16

US Classification:

710 45, 712 21

Abstract:

One embodiment of the present invention performs peripheral operations in a multi-thread processor. A peripheral bus is coupled to a peripheral unit to transfer peripheral information including a command message specifying a peripheral operation. A processing slice is coupled to the peripheral bus to execute a plurality of threads. The plurality of threads includes a first thread sending the command message to the peripheral unit.

Appl. No.:

11/047410

Inventors:

Jeffrey L. Nye - Austin TX, US
Sam B. Sandbote - Dallas TX, US

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

G06F 3/00
G06F 15/167
G06F 13/00
G06F 9/30

US Classification:

710 52, 710 57, 365 4911, 709213, 711100, 712204, 712205, 712217, 712233, 712237

Abstract:

A method and apparatus for adaptive buffer sizing adjusts the size of the buffer at different levels using a “high water mark” to different levels for different system conditions. The high water mark is used by the buffer logic as an indication of when to assert the buffer “Full” flag. In turn, the full flag is used by the instruction fetch logic as an indication of when to stop fetching further instructions.

International Classification:

H04B 7/204

US Classification:

370319, 370230, 370412, 370413, 370414, 370419

Abstract:

The present invention is a technique to select an input port. A database stores records of input ports for a plurality of communication channels. Each of the records includes a timestamp and a ready status. The timestamp indicates a most recent service time. A selector selects one of the input ports based on the timestamp and the ready status. A listener updates the records.
