ARM7TDMI Processor Functional Description

This hardware component is a ARM7TDMI processor core. This is only an ISS, which should be wrapped with an IssWrapper.

The simulation model is actually an instruction set simulator with an ARM7TDMI pipeline.

Currently it only exists in bigendian form.

Component definition

Available in source:trunk/soclib/soclib/lib/arm7tdmi/metadata/arm7tdmi.sd

Usage

ARM7TDMI has no parameters. 

Uses('iss_wrapper', iss_t = 'common:arm7tdmi')

Before compiling any SoClib simulator using the ARM7TDMI you will need to download the UNISIM ([http:\\www.unisim.org]) library (well, just a piece of it, the unisim_lib). To do so just download it using svn from ​https://unisim.org/svn/devel/unisim_lib with the following command:

You will have to enter a username and password. If you do not have access to the UNISIM development, you can simply use 'guest'/'guest' for username and password respectively. Once you have downloaded UNISIM you will need to create a link in trunk/soclib/lib/arm7tdmi/include/iss/ and trunk/soclib/lib/arm7tdmi/src/iss/ to <your_path_to_unisim_lib>/unisim.

If you wish you can download the full UNISIM library by downloading unisim_tools and unisim_simulators:

The previous files use the ARM7TDMI implementation provided in the UNISIM library.

Template parameters

This component has no template parameters.

Constructor parameters

Interrupts

UNDER DEVELOPMENT The handling and prioritization of the interrupts is deferred to software.

Ports

None, it is to the wrapper to provide them.
