The Compilation Toolchain Cross-Compilation for Embedded Systems Prof. Andrea Marongiu ([email protected]) Toolchain The toolchain is a set of development tools used in association with source code or binaries generated from the source code • Enables development in a programming language (e.g., C/C++) • It is used for a lot of operations such as a) Compilation b) Preparing Libraries Most common toolchain is the c) Reading a binary file (or part of it) GNU toolchain which is part of d) Debugging the GNU project • Normally it contains a) Compiler : Generate object files from source code files b) Linker: Link object files together to build a binary file c) Library Archiver: To group a set of object files into a library file d) Debugger: To debug the binary file while running e) And other tools The GNU Toolchain GNU (GNU’s Not Unix) The GNU toolchain has played a vital role in the development of the Linux kernel, BSD, and software for embedded systems. The GNU project produced a set of programming tools. Parts of the toolchain we will use are: -gcc: (GNU Compiler Collection): suite of compilers for many programming languages -binutils: Suite of tools including linker (ld), assembler (gas) -gdb: Code debugging tool -libc: Subset of standard C library (assuming a C compiler). -bash: free Unix shell (Bourne-again shell). Default shell on GNU/Linux systems and Mac OSX. Also ported to Microsoft Windows. -make: automation tool for compilation and build Program development tools The process of converting source code to an executable binary image requires several steps, each with its own tool. -

Risc I: a Reduced Instruction Set Vlsi Computer
RISC I: A REDUCED INSTRUCTION SET VLSI COMPUTER DAVID A. PATTERSON and CARLO H. SEQUIN Computer Science Division University of California Berkeley, California ABSTRACT to implement CISC is the best way to use this “scarce” resource. The Reduced Instruction Set Computer (RISC) Project investigates an alternatrve to the general trend toward computers wrth increasingly complex instruction sets: With a The above findings led to the Reduced Instruction Set proper set of instructions and a corresponding architectural Computer (RISC) Project. The purpose of the project is design, a machine wrth a high effective throughput can be to explore alternatives to the general trend toward achieved. The simplicity of the instruction set and addressing architectural complexity. The hypothesis is that by modes allows most Instructions to execute in a single machine cycle, and the srmplicity of each instruction guarantees a short reducing the instruction set, VLSI architecture can be cycle time. In addition, such a machine should have a much designed that uses the scarce resources more effectively shorter design trme. than CISC. We also expect this approach to reduce design time, the number of design errors, and the This paper presents the architecture of RISC I and its novel execution time of individual instructions. hardware support scheme for procedure call/return. Overlapprng sets of regrster banks that can pass parameters directly to subrouttnes are largely responsible for the excellent Our initial version of such a computer is called RISC I. performance of RISC I.
