Introduction

1.1 Introduction

The DM6467 HD-VICP Subsystem functional simulator, available within the Code Composer Studio Integrated Development Environment (IDE), simulates the DM6467 HD-VICP based devices. Entire codec development as well as optimization for video standards (e.g. H.264, MPEG2/4, and VC1) is performed on DM6467 HD-VICP Subsystem functional simulator. It also supports multiple high definition Imaging Coprocessor (IMCOP).

1.2 Supported Configuration

2.1 Installing DM6467 HD-VICP Subsystem Functional Simulator

Follow these steps to install the DM6467 HD-VICP Subsystem functional simulator:

1) Install Code Composer Studio v3.2 or v3.3 on your machine.

2) Run the DM6467 HD-VICP Subsystem functional simulator installer. This is a self extracting and self installing patch.

3) This executable creates a folder named DM6467 in the location <install directory>\drivers\c64plus_sim_ua_releases\DM6467

2.2 Setting DM6467 HD-VICP Subsystem Functional Simulator in Code Composer Studio

Follow these steps to setup DM6467 HD-VICP Subsystem functional simulator in Code Composer Studio v3.2:

1. Click start button in the taskbar and select Setup Code Composer Studio v3.2 or v3.3 from the Programs menu. Code Composer Studio Setup screen is displayed.

2.3 Parallel Debug Manager

PDM (Parallel Debug Manager) enables the usage of multiple processors in the system. For example, to use GEM and ARM968 processors in parallel, it is important to load the program on the respective processor, and then run it from PDM. This would provide execution of an event in order to simulate both GEM and ARM968 at the same time. The PDM window also shows the status of each processor whether it is in ‘RUN’ state, or in ‘HALTED’ state.

For more details on PDM, refer Code Composer Studio online help.

3.1 Effective Usage of Simulator

3.1.1 Optimal Performance of Simulator

When you invoke DM6467 HD-VICP Subsystem functional simulator in Code Composer Studio, four processors are displayed in the System pane (two ARM968 and one C64+ (TMs320c6400) and a Host ARM). See Figure 2-7.

If you run the simulation from PDM without selecting any particular processor, then all the processors will be clocked. The processor that does not execute any test case causes performance degradation of the simulator.

Follow these guidelines to avoid performance degradation of the simulator:

1. To execute a test case on GEM, run the simulation from GEM (C64+) IDE and not from PDM window.

2. To execute a test case on one of the ARMs of IMCOPs, run the simulation from the corresponding ARM IDE and not from PDM window.

3. To execute a test case on any two IDEs, follow these steps:

a. Load the test case on corresponding IDEs

b. From PDM, select any two processors under System pane

c. From the Group menu, select <Highlighted CPUs>

d. With the desired CPUs selected, click RUN icon in PDM window

4. To execute a test case on IMCOP0, IMCOP1, and GEM, load the test case on corresponding IDEs (ARM0 for IMCOP0, ARM1 for IMCOP1, and C64+ for GEM), group them, and click RUN icon in PDM window.

5. To execute a test case on IMCOP0, IMCOP1, GEM, and Host ARM, load the test case on corresponding IDEs and click RUN icon in PDM window.

3.1.2 Shared Memory Debug Accesses

Shared memory in the DM6467 HD-VICP Subsystem functional simulator is visible from GEM and IMCOPs. To access shared memory, click View->Memory from any of the processor window. In the memory window, you can modify the shared memory by using debug-write.

Consider the following points while debugging access to shared memories:

1. The shared memory present in one CPU would reflect in the other CPU only if a manual refresh is done in the latter. To refresh the shared memory, right click and choose Refresh in the memory window. Memory refresh is not required for the debugger window where you actually perform the changes.

Simulator Usage

2. Debug access (read/write is allowed only for “Read Only” memory locations. You can modify Read Only memory only if the access is allowed by CPU or DMA. To debug-write a memory location, choose View->Memory and manually modify.
