= Processor Functional Description =

This hardware component is a Mips-32 processor core.

This ISS uses the [wiki:Component/Iss2Api ISS2 API]
and can be wrapped in a CABA or TLM-T [wiki:Component/VciXcacheWrapper Wrapper].

It implements all instructions defined in the MIPS32 architecture specification, with the following limitations:
 * The floating point instructions are supported, FPU exception detection is partially implemented
 * The Mips virtual memory instructions are not supported. The MMU is implemented as an external TLB (SoCLib generic MMU) in the [wiki:Component/VciVcacheWrapper VciVcacheWrapper] component. 

Both little-endian and big-endian implementations are available.

== Template parameters ==
 
This component has no template parameters.

== Interrupts ==

Mips defines 6 interrupts lines.
The handling and prioritization of the interrupts is deferred to software.

== Ports ==

None, it is to the wrapper to provide them.

== Debug and traces ==

When built with SOCLIB_MODULE_DEBUG defined (for example by calling
soclib-cc with "-b common:mips32 -b common:mips32el"), some debug messages
are available, controlled with the [wiki:Component/Iss2Api ISS2]
set_debug_mask() method. By default all messages are enabled;
see source:trunk/soclib/soclib/iss/mips32/include/mips32.h for possible
values.
