ARC MetaWare Compiler

The MULTI Integrated Development Environment for the ARC processor includes the ARC MetaWare C/C++ compiler. ARC’s MetaWare compiler is highly optimized and robust. Some of the most notable features include:

	Intrinsics for users to define their own instruction
	Intrinsics for core and auxiliary register access
	Numerous optimizations aimed at smaller and faster code, including zero-delay loops, conditional instructions,delay-slot filling, loop unrolling, common subexpression elimination, instruction scheduling, etc.
	Big and little endian addressing mode
	Small-data area
	Run-time library source code
	Extensive linker command language for the control of text and data placement
	Compiler support for interrupt handling
	Enhanced inline assembly

Run-Time Libraries
A complete implementation of C libraries is included in compiler distributions. In addition, C++ iostream libraries are provided. Full featured start-up code and libraries include automatic copy of data from ROM to RAM and system call emulation.

The MULTI Integrated Development Environment

MULTI provides a host-based (Windows, Linux or UNIX workstation) graphical environment for ARC target development. Host-target connectivity is provided through a variety of means, depending on the target environment. MULTI supports hardware connectivity, including the ARCangel™-3 evaluation board. These targets can be accessed through the following interfaces:
	Bare Board Access (no RTOS or ROM Monitor)—MULTI supports tartgets connected through JTAG headers on the board. ARC boards are supported with the Green Hills Probe, Slingshot, and the MetaWare parallel port interface.
	Custom RTOS Support—MULTI supports ARC boards running Express Logic's ThreadX RTOS. MULTI provides kernel multitask-aware debugging. Special commands allow tasks to be stopped upon system events such as task creation.
	Instruction Set Simulator and Cycle Accurate Simulator—The ARCserv debug server is a utility that connects to the MetaWare Instruction Set Simulator (ISS) and Cycle Accurate Simulator (CAS). Both simulators interpretively execute ARC programs on the host PC or workstation without the need for target hardware. In addition, developers can extend the simulators with their own extension instructions, core registers, auxiliary registers, and condition codes to create a completely customized model of their own processor. The Cycle Accurate Simulator provides 100% cycle accuracy. Both simulators can be configured to simulate instruction and data caches, which can be viewed graphically in MULTI. Both simulators keep track of count information for each instruction, which includes things like: Instruction hit counts Cycle count Killed cycles due to branches Stall cycles Function entry counts
