ROM initialization
Friday 14 June 2024, by // Tools
System on chip contains 64 Kbytes of read only memory between addresses $FFFF0000 and $FFFFFFFF. This memory is created with RAM blocks and initialized in a file created by memblcks.rpl tool.
memblcks.rpl is a program written in RPL/2 and takes a SREC file generated by A09 assembler in 32 bits mode. It splits S-records into bits arrays to create a usable 27F512.vhd file.
This tool is downloadable from ftp site.
