In In this technical report, we present the application of formal verification
to digital signal processors of the family ADSP-2100 using the HOL (Higher
Order Logic) theorem prover. To solve the problem of complexity related
to the big number of parameters of the processor, we used a structured
method based on our knowledge about this processors family. In this method,
we worked on the units of the processor as separate sub-systems in order
to simplify their specifications by omitting the internal signals. We showdetails
of the specification and verification strategies used and displayexperimental
results as well the lessons learned..
