BVM: Storing constants, etc.

[thosakwe]

The MMU

From now on, upon starting an instance of the BVM, it will initialize a 65KB, read-write region of memory for constants. The first 16KB of the file will be copied here. This makes it stupid-simple to get constant values into a Bonobo program.

Executable memory starts at 0x10000. This memory cannot be read or written, only executed.

The very first 32 bits of the program are a pointer to the first routine that should be called. After constants are copied in to R/W memory, the CPU jumps to the address, and runs until completion.
