Open Source Apache 2.0

Description
This is a platform representing a MIPS Malta development board. It provides the peripherals required to boot and run a Linux Operating System. A single MIPS32 architecture processor is instantiated in this platform. This instance could be duplicated to instantiate further processors to easily create an SMP platform. Attributes are provided for configuration of the generic ISA model for a specific processor. The processor model is configured to operate as a MIPS32 4KEc. The main SDRAM and Flash memory is modeled using RAM models. Both are initialised in places by the 'SmartLoaderLinux'. The SmartLoaderLinux allows ease of use of changing kernel command lines, loading an initial ram disk and creating the boot flash(s). The operation of the SmartloaderLinux is configured using a number of attributes. The kernel attribute of the SmartLoaderLinux and the imagefile of the processor must be consistent. NOTE: a non Mips Malta peripheral 'AlphaDisplay16x2' has been defined in this platform definition to be used for demo purposes. It should be removed if there is a memory error in the address space 0x18000100-0x18000103 If this platform is not part of your installation, then it is available for download from www.OVPworld.org/MIPSuser.

Limitations
Verification has only been carried out using Little Endian memory ordering.

Interrupts and FIFOs are supported.
Registers are aligned on 1 byte boundaries.

Limitations
Resolution of the baud rate is limited to the simulation time slice (aka quantum) size.
