Converter for converting data type, chip, electronic device, and method therefor

A converter for data type conversion, comprising:

• a first conversion stage (L1) configured to receive first type data and first descriptive information about the first type data, and according to the first descriptive information convert the first type data into an intermediate result;
• and
• a second conversion stage (L2) configured to receive second descriptive information about second type data, and according to the second descriptive information, convert the intermediate result into the second type data,
• wherein the first conversion stage (L1) includes a first receiving unit (Rx1) and a first extracting unit (E1), and the first descriptive information includes a first data type of the first type data and a first exponent bit of the first type data, wherein
• the first receiving unit (Rx1) is configured to receive the first type data and the first descriptive information;
• and
• the first extracting unit (E1) is configured to, from the first type data and the first descriptive information, extract an intermediate sign bit (Msign), an intermediate data bit (Mdata), and an intermediate exponent bit (Mshift) as the intermediate result,
• wherein the second conversion stage (L2) includes a second calculation unit (C2), a second pre-output parsing unit (P2), and a second data recovery unit (R2), wherein
• the second calculation unit (C2) is configured to receive the intermediate result and the second descriptive information, and according to the intermediate result and the second descriptive information, calculate a second intermediate result;
• the second pre-output parsing unit (P2) is configured to calculate a pre-output data bit (Pdata) and a pre-output sign bit (Psign) according to the second intermediate result;
• and
• the second data recovery unit (R2) is configured to generate the second type data according to the pre-output data bit (Pdata) and the pre-output sign bit (Psign).
