Design and Verification of Vector Floating Point Coprocessor VFP-A
Xi Jin · 2009
A high performance floating point coprocessor VFP-A was designed and verified,which was in accordance with interface specification of ARM11 coprocessor. To meet customers’ requirement,the circuit was compatible with VFP11 instruction set and supported extension instructions. Designed in 90 nm CMOS technology,the high performance and low-cost VFP-A achieved a clock frequency up to 600 MHz. By combining code coverage driver with function coverage driver,verification process was accelerated,and verification flexibility was also improved. Application tests showed that the circuit performance was comparable with ARM11’s vector floating point coprocessor VFP11.
