Hardware Implementation Parameters Dialog Box Overview

Specifies parameters of the target hardware implementation.

The Hardware Implementation parameters dialog box appears as follows by default. (The long and native word size values shown are for a 32-bit MATLAB host computer.) In this case, the test hardware and the deployment hardware are the same and you use the Embedded hardware pane to set the hardware properties for both.

Displaying the Dialog Box

To display the Hardware Implementation dialog box for Embedded MATLAB Coder, follow these steps at the MATLAB command prompt:

Define a configuration object variable for hardware implementation in the MATLAB workspace by issuing a constructor command like this:
```
hwi_cfg=emlcoder.HardwareImplementation;
```
Open the property dialog box using one of these methods:
- Double-click the configuration object variable in the MATLAB workspace
- Issue the open command from the MATLAB prompt, passing it the configuration object variable, as in this example:
```
open hwi_cfg;
```
The dialog box displays on your desktop.

Hardware Implementation Parameters

The following table describes the hardware implementation parameters for Embedded MATLAB Coder:

Parameter Equivalent Command-Line Property and Values
(default in bold) Description

Device vendor ProdHWDeviceType
string, 'Generic->MATLAB Host Computer' Specify manufacturer of hardware you will use to implement the production version of the system.

Device type ProdHWDeviceType
string, 'Generic->MATLAB Host Computer' Specify type of hardware you will use to implement the production version of the system.

Number of bits: char ProdBitPerChar
integer, 8 Describe length in bits of the C char data type supported by the deployment hardware.

Number of bits: short ProdBitPerShort
integer, 16 Describe length in bits of the C short data type supported by the deployment hardware.

Number of bits: int ProdBitPerInt
integer, 32 Describe length in bits of the C int data type supported by the deployment hardware.

Number of bits: long ProdBitPerLong
integer, host-specific value (32 or 64) Describe length in bits of the C long data type supported by the deployment hardware.

Number of bits: native word size ProdWordSize
integer, host-specific value (32 or 64) Describe microprocessor native word size for the deployment hardware.

Byte ordering ProdEndianess
'Unspecified', 'LittleEndian', 'BigEndian' Describe significance of the first byte of a data word for the deployment hardware.

Signed integer division rounds to ProdIntDivRoundTo
'Undefined', 'Zero', 'Floor' Describe how your compiler rounds the result of dividing one signed integer by another to produce a signed integer quotient.

Shift right on a signed integer as arithmetic shift ProdShiftRightIntArith
true, false Describe whether your compiler implements a signed integer right shift as an arithmetic right shift.

None

ProdEqTarget
true, false

Specify whether the test hardware differs from the deployment hardware.

Note By default they are the same.

Dependencies:

Setting this parameter to true disables the Emulation hardware (code generation only) subpane.
Setting this parameter to false enables the Emulation hardware (code generation only) subpane. This subpane is used to specify the test hardware properties.
See Emulation Hardware Subpane

Emulation Hardware Subpane

The Hardware Implementation parameters dialog box displays the Emulation hardware (code generation only) subpane when the test hardware and the deployment hardware differ. In this case, you use the Embedded hardware (simulation and code generation) subpane to specify the deployment hardware properties and the Emulation hardware (code generation only) pane to specify the test hardware properties.
