This document is the TEMU (Terma Emulator) Software Users Manual. It describes the fundamental concepts and general usage of the TEMU libraries and command line interface.

TEMU is a multi-achictecture microprocessor emulator. It currently supports the ARMv7, SPARCv8 and PowerPC instruction sets. Currently this includes: ERC32, LEON2, LEON3, LEON4, Cortex-R4/5 and PPC750. The emulator can emulate multi-core processors.

TEMU is a full system emulator. It is capable of emulating (multi-core) microprocessors, memory and peripherals. Different devices are written as plugins. Including CPUs, memory and device modules. In-fact, systems are constructed by connecting different modules together. Thus, there is no hard-wiring of devices to any particular memory layout.

To give an example, in order to construct a LEON2 processor, one would first create and connect the CPU core, ROM, RAM and LEON2 SoC components.

There are two user interfaces for TEMU, the Command Line Interface (CLI) and the libraries (API). The CLI offers an interactive tool for running the emulator by itself. While the API allows the user to integrate the emulator with other simulators.
