VciRam

Functional Description

This VCI target is an embedded SRAM controller. This hardware component handles independent memory segments. Each segment is defined by a base address and a size (number of bytes). Both the base and the size parameters must be multiple of 4. The segments allocated to a given instance of this component are defined in the Mapping Table.

Each segment is implemented as a dynamically allocated array in the constructor.

A MultiRam will initialize its segments from a binary if an !ElfLoader? is attached to it.

CABA Implementation

• interface : source:trunk/soclib/soclib/module/internal_component/vci_ram/caba/source/include/vci_ram.h​
• implementation : source:trunk/soclib/soclib/module/internal_component/vci_ram/caba/source/src/vci_ram.cpp​

TLM-T Implementation

Constructor parameters

• Uninitialized VciRam

  VciRam(
       sc_module_name name,                     // Instance name
       const soclib::common::IntTab &index,     //  Target index
       const soclib::common::MappingTable &mt)  // Mapping Table
  

• Elf-Initialized VciRam

You may load a binary file, by creating a loader:

soclib::common::ElfLoader loader( "a.out" );
VciMultiRam(
     sc_module_name name,                     // Instance name
     const soclib::common::IntTab &index,     //  Target index
     const soclib::common::MappingTable &mt,  // Mapping Table
     soclib::common::ElfLoader &loader); // Loader

On reset, any loadable segment in ELF file will be reloaded .
