This paper presents the design of a new bit-serial floating-point unit (FPU). It has been developed for the processors of the instruction systolic array (ISA) parallel computer model. In contrast to conventional bit-parallel FPUs the bit-serial approach requires a different data format. Our FPU uses an IEEE compliant internal floating-point format that allows a fast least significant bit (LSB)-first arithmetic and can be efficiently implemented in hardware.
