riscv_ctg.constants.gen_sign_dataset(bit_width)

Function to generate the signed data set with datapoints from the following patterns.

• alternating ones

• alternating zeros

• walking ones

• walking zeros

• max val

• min val

• max val/2

• min val/2

• [-10,10]

param bit_width

integer defining the size of the input

type bit_width

int

return

a list of integers

riscv_ctg.constants.gen_sp_dataset(bit_width, sign=True)

Function generates a special dataset of interesting values:

• [3*1/3,3*2/3,5,5*1/5,5*2/5]

• sqrt (bit_width<<1)

• +/-1 variants of the above

param bit_width

Integer defining the size of the input

param sign

Boolen value specifying whether the dataset should be interpreted as signed numbers or not.

type sign

bool

type bit_width

int

return

a list of integers

riscv_ctg.constants.gen_usign_dataset(bit_width)

Function to generate the unsigned dataset

• alternating ones

• alternating zeros

• walking ones

• walking zeros

• max val

• min val

• max val/2

• min val/2

riscv_ctg.constants.twos(val, bits)

A function to generate the two’s complement of a number which is of arbitrary width

Parameters

• val (Union[int, str]) – the input which can be either a hexadecimal string or integer

• bits (int) – size of the input in terms of bits.

Returns

integer value in 2’s complement representation
