Smalltalk Run-Time Architecture Virtual Machine + Image + Changes and Sources • • • Image = bytecodes Sources and changes = code (text) S. Ducasse 3

Runtime Architecture • • • The byte-code is in fact translated into native code by a just-in-time compiler. The source and the changes are not necessary for interpreting the byte-code, this is just for the development. Normally they are removed for deployment. An application can be delivered as some byte-code files that will be executed with a VM. The development image is stripped to remove the unnecessary development components. S. Ducasse 4
