This chapter describes cpu3000 processor test
cpu3000 runs via the test controller and provides a basic test of the
functionality of the PA8500. cpu3000 requires a minimum of one
processor with its associated SPAC and two EWMBs. Included in the
testing are most of the instruction set, the ALU, general, space and
control registers, external interrupts, RDRs, TLB RAM, the instruction
cache, and the data cache. The tests are grouped together in five classes
beginning with verification of the most basic functionality and
progressing toward more complex functionality. Each class has a set of
subtests that target specific functionality.
