coreblocks.func_blocks.fu.fpu.fpu_error_module module

class coreblocks.func_blocks.fu.fpu.fpu_error_module.FPUErrorMethodLayout

Bases: object

FPU error checking module layouts for methods

Parameters

fpu_params: FPUParams

FPU parameters

__init__(*, fpu_params: FPUParams)

input_inf is a flag that comes from previous stage. Its purpose is to indicate that the infinity on input is a result of infinity arithmetic and not a result of overflow

Parameters

fpu_params: FPUParams

FPU rounding module parameters

Attributes

error_checking_request: Method

Transactional method for initiating error checking of a floating point number. Takes ‘error_in_layout’ as argument Returns final number and errors as ‘error_out_layout’
