What is host and target machine?
The host computer is also called as Development Platform. It is a general purpose computer. Once a program has been written, compiled, assembled and linked, it is moved to the target platform. 1.2.2 Performance of Target machine. The output binary image is executed on the target hardware platform.
What is a target machine?
A target machine is a system (or systems) that runs the 4Test Agent, which is the software process that translates the commands in your scripts into GUI-specific commands, in essence, driving and monitoring your applications under test. Target machines can be Windows systems.
What is a target system in embedded system?
The target embedded system might offer a dynamic loader, a link loader, a monitor, and a debug agent. A set of connections might be available between the host and the target system. These connections are used for downloading program images from the host system to the target system.
What is host target development model?
Most software development is host-target development. You use an IDE on a host machine to develop the software, which is transferred to a target machine for execution. Open source development involves making the source code of a system publicly available.
What is host device?
A host is any hardware device that has the capability of permitting access to a network via a user interface, specialized software, network address, protocol stack, or any other means. Some examples include, but are not limited to, computers, personal electronic devices, thin clients, and multi-functional devices.
What is the purpose of an embedded system?
An embedded system is a small computer that forms part of a larger system, device or machine. Its purpose is to control the device and to allow a user to interact with it. They tend to have one, or a limited number of tasks that they can perform.
How do you calculate cost of instruction?
Instruction costs : Instruction cost = 1+cost for source and destination address modes. This cost corresponds to the length of the instruction. Address modes involving registers have cost zero.
What are different issues in code generation?
The following issue arises during the code generation phase:
- Input to code generator –
- Target program –
- Memory Management –
- Instruction selection –
- Register allocation issues –
- Evaluation order –
- Approaches to code generation issues: Code generator must always generate the correct code.
How many basic activities are there in every software process model?
four basic process activities
The four basic process activities of specification, development, validation and evolution are organized differently in different development processes. In the waterfall model, they are organized in sequence, whereas in incremental development they are interleaved.
