The present disclosure relates to a floating-point computation circuit comprising: an internal memory () storing one or more floating-point values in a first format; status registers () defining a plurality of floating-point number format types associated with corresponding identifiers, each format type indicating at least a maximum size (BIS, MBB); and a load and store unit () for loading floating-point values from and storing floating-point values to an external memory (), the load and store unit () being configured: to receive, in relation with a first store operation, a first floating-point value from the internal memory () and a first of said identifiers; and to convert the first floating-point value from the first format to a first external memory format having a maximum size (BIS, MBB) defined by the floating-point number format type designated by the first identifier.

Method and device for variable precision computing

The present disclosure relates to a method of storing, by a load and store circuit or other processing means, a variable precision floating point value to a memory address of a memory, the method comprising: reducing the bit length of the variable precision floating point value to no more than a size limit, and storing the variable precision floating point value to one of a plurality of storage zones in the memory, each of the plurality of storage zones having a storage space equal to or greater than the size limit (MBB).
