Hello All,
I have some questions regarding converting SPARC_SE model which is SPARC V9 to SPARC V8. The major difference between the two, stated on wikipedia is as follows: "The 32-bit SPARC V8 architecture is purely big-endian. The 64-bit SPARC V9 architecture utilizes big-endian instructions, but can access data in either big-endian or little-endian byte order, chosen either at the application instruction (load/store) level or at the memory page level (via an MMU setting). The latter is often used for accessing data from inherently little- endian devices, such as those on PCI buses." 1. Assuming the only difference being 64-bit to 32-bit conversion, is it a considerable amount of work? I would think I have to make the changes throughout the simulator but was wondering if there was an easier way to do so. 2. What would be the initial steps to do so? I am not an expert at M5 so I haven't really done much 'modification' to the model. Any tips on where I should start would be great. Thank you. _______________________________________________ m5-users mailing list [email protected] http://m5sim.org/cgi-bin/mailman/listinfo/m5-users
