Embodiment Construction

[0039] In this embodiment, after the user sets the character identification, word length and calibration, the parameters set and fixed-point numbers or floating-point numbers are input to the conversion device through the operation interface, and the conversion device will input according to the character identification, word length and calibration. Convert the fixed-point number to the corresponding floating-point number, or convert the input floating-point number to the corresponding fixed-point number, and then output the converted fixed-point number and floating-point number to the chip that needs to be verified and the software verification algorithm for corresponding operation processing , when the operation result of the chip is consistent with the operation result of the algorithm, it is determined that the hardware operation and software operation of the chip are correct.

[0040] As shown in Figure 1, the main implementation process of chip verification in this embodi...

Abstract

The invention discloses chip verification method and system. The method includes following steps: using operating interface to input fixed-point number or floating-point number to the conversion device; converting the fixed point number into the corresponding floating one according to the symbol mark, word length, and calibrate or converting the floating point number into the fixed one; outputting them to the verified chip and software verification algorithm to process corresponding operation; comparing the chip operative result with the algorithm operative result; when they are the same the hardware and software operation of the chip are right. The invention can be used to increase chip verification efficiency and precision.

Description

technical field [0001] The invention relates to the field of computers, in particular to a chip verification method and system. Background technique [0002] In the existing chip verification process, the user needs to set the character ID and word length, and then select the required calibration in the calibration group corresponding to the set character ID and word length, and manually convert the input fixed-point number ( or floating-point number) to convert the corresponding floating-point number (or fixed-point number); after the conversion, if it is judged that the precision of the converted number does not meet the requirements, the user needs to re-select the calibration, and then manually convert through the conversion algorithm or formula, and further Judge whether the converted number meets the precision requirement until the converted data meets the precision requirement; when verifying the existing chip, the user may need to repeat the manual conversion of the ...
