摘要： Embodiments of a processor are disclosed for performing arithmetic operations on a machine independent number format. The processor may include a floating point unit, and a number unit. The number format may include a sign/exponent block, a length block, and multiple mantissa digits. The number unit may be configured to perform an operation on two operands by converting the digit format of each mantissa digit of each operand, to perform the operation using the converted mantissa digits, and then to convert each mantissa digit of the result of the operation back into the original digit format.

摘要： A decimal floating-point fused multiplier-adder (DFMA) for carrying out addition and multiplication operations on a first operand, a second operand and a third operand includes a multiplication module for multiplying a first significand of the first operand and a second significand of the second operand to output an intermediate product. The DFMA further includes a pre-alignment module for shifting a third significand of the third operand to output a pre-aligned addend, an addition module for adding the intermediate product and the pre-aligned addend to output an intermediate sum, and a post-alignment module for shifting the intermediate sum based on the shifting of the third significand of the third operand and a preferred exponent to output a post-aligned sum. The post-alignment module of the DFMA may also include a leading non-zero digit detection that receives the intermediate sum as its operand. The post-alignment module of the DFMA may also include a combined rounder-conversion module.

摘要： Embodiments of an apparatus are disclosed for performing arithmetic operations on provided operands. The apparatus may include a fetch unit, and an arithmetic logic unit (ALU). The fetch unit may be configured to retrieve two operands responsive to receiving an instruction, wherein the operands include binary-coded decimal values. The ALU may be configured to scale a value of each of the operands, and then compress the scaled values of the operands. The compressed values of the operands may include fewer data bits than the corresponding scaled values. The ALU may be further configured to estimate a portion of a result of the operation dependent upon the compressed values of the operands.

摘要： A system and method for detecting decimal floating point data processing exceptions. A processor accepts at least one decimal floating point operand and performs a decimal floating point operation on the at least one decimal floating point operand to produce a decimal floating point result. A determination is made as to whether the decimal floating point result fails to maintain a preferred quantum. The preferred quantum indicates a value represented by a least significant digit of a significand of the decimal floating point result. An output is provided, in response to the determining that the decimal floating point result fails to maintain the preferred quantum, indicating an occurrence of a quantum exception. A maskable exception can be generated that is immediately trapped or later detected to control conditional processing.

摘要： A floating point multiplier-accumulator (MAC) multiplies and accumulates N pairs of floating point values using N MAC processors operating simultaneously, each pair of values comprising an input value and a coefficient value to be multiplied and accumulated. The pairs of floating point values are simultaneously processed by the plurality of MAC processors, each of which outputs a signed integer form fraction and a maximum exponent. A range estimator forms a possible range of values from the exponent differences and determines an adder precision. The integer form fractions are summed using the adder precision, a sign bit is extracted, and a floating point value is output. Each MAC processor provides its integer form fraction with a precision determined by the MAC processor's exponent difference.
