With the addition of 32-bit wide, 16-megabyte DRAM, Tiny030 is capable of running a varieties of application software quickly. In this project we'll rerun the EhBASIC and memory diagnostic of Stage 3, add a new memory diagnostic for 16-meg DRAM, and do a benchmark of EhBASIC running in DRAM and compare that to EhBASIC running in 8-bit RAM.
The existing ROM monitor runs fine in stage 4 hardware. It now can access memory located from 0x1000000 to 0x1FFFFFF.
I wrote a memory diagnostic to test 16 meg of DRAM
