Filed:

Feb 22, 2002

Appl. No.:

10/081431

Inventors:

Trinh Huy Nguyen - Pflugerville TX, US

Assignee:

Freescale Semiconductor, Inc. - Austin TX

International Classification:

G06F007/52

US Classification:

708627, 708628, 708629

Abstract:

A multiplier () forms a product from two signed operands without performing a sign extension of the multiplicand (A). A modified Booth's recoding of the multiplier operand (B) is begun immediately without being delayed by a sign extension operation. While recoding and partial product generation is occurring, a determination is made in parallel whether or not a sign extension adjustment term must be created. When needed, a value equal to (−B) (2), where N is equal to a bit width of the multiplicand (A), is formed in parallel with the recoding and partial product generation. The sign extension adjustment term is coupled to a plurality of carry save adders () that compress a plurality of partial products to a sum term and a carry term. A final add stage combines the sum term and carry term to provide a product with correct sign extension.

International Classification:

G01N 33/00

US Classification:

436128, 436 56, 436111, 436173, 436175

Abstract:

A method of identification and quantitative analysis of aldehydes and/or ketones in a sample by mass spectrometry using stable isotope labeled oxime internal standards or stable isotope labeled hydrazone internal standards is provided. Stable isotope labeled oxime internal standards are synthesized by reaction of an authentic sample of aldehydes and/or ketones with a stable isotope labeled alkoxylamine reagent while stable isotope labeled hydrazone internal standards are synthesized by reaction of an authentic sample of aldehydes and/or ketones with a stable isotope labeled alkylhydrazine reagent. A non labeled version of the stable isotope labeled reagent is used to convert aldehydes and/or ketones in the sample to the non labeled version of the stable isotope labeled oxime or hydrazone internal standards.

Abstract:

Method of identification and quantitative analysis of alcohol(s) in a sample by mass spectrometry using stable isotope labeled internal standard is provided. Said internal standard is prepared by reaction of an authentic sample of said alcohol with a stable isotope labeled reagent, and is added to a sample containing said alcohol. Said alcohol in said sample is then quantitatively converted to a chemical compound of identical structure, except the stable isotope atoms, as that of said internal standard using a non-labeled reagent. Said sample is then extracted and the extract is analyzed by mass spectrometry. Identification and quantification of said alcohol are made from a plot of ion ratio of said converted alcohol to said internal standard versus alcohol concentration.

Abstract:

Method of identification and quantitative analysis of carboxylic acid(s) in a sample by mass spectrometry using stable isotope labeled internal standard is provided. Said internal standard is prepared by reaction of an authentic sample of said carboxylic acid with a stable isotope labeled reagent, and is added to a sample containing said carboxylic acid. Said carboxylic acid in said sample is then quantitatively converted to a chemical compound of identical structure, except the stable isotope atoms, as that of said internal standard using a non-labeled reagent. Said sample is then extracted and the extract is analyzed by mass spectrometry. Identification and quantification of said carboxylic acid are made from a plot of ion ratio of said converted carboxylic acid to said internal standard versus carboxylic acid concentration.

Appl. No.:

11/226040

Inventors:

Dimitri Tan - Austin TX, US
Trinh H. Nguyen - Pflugerville TX, US

Assignee:

Freescale Semiconductor, Inc. - Austin TX

International Classification:

G06F 7/00

US Classification:

708205

Abstract:

A data processor includes a first bit field of a first plurality of bits representing a mantissa of a floating point number and a second bit field of a second plurality of bits representing an exponent of the floating point number. The first plurality of bits is partitioned into a plurality of regions, each of the plurality of regions comprises more than one bit of the first plurality of bits. A leading zero anticipator or other type of leading bit indication circuit is coupled to each region and determines a position of a leading bit of the first plurality of bits. A normalizer is coupled to receive a region of the plurality of regions that contains the leading bit, the normalizer may normalize or denormalize the region to produce a normalized or denormalized floating point number.

International Classification:

G06F 12/00

US Classification:

711154, 711170, 711E12084

Abstract:

A data processing device and methods thereof are disclosed. The data processing device can operate in three different modes. In a first, N-bit mode, the data processing device performs memory accesses based on N-bit values and performs arithmetic operations using N-bit values. In a second, hybrid N-bit/M-bit mode, the data processing device performs memory accesses based on M-bit values, where M is less than N, and performs arithmetic operations using N-bit values. In a third, M-bit mode, the data processing device performs memory accesses based on M-bit values and performs arithmetic operations using M-bit values. The three modes provide for compatibility with a wide range of applications. Further operation in the M-bit mode can provide a power savings when implementing applications compatible with that mode.
