Dear friends,

I recently read in book that clipping algorithms are implemented in hardware
rather than in software for performance reasons. As I'am new to graphics I have a doubt regarding this. What is actually meant when we say an algorithm is implemented in hardware. What is the process of implementing an algorithm in hardware.

regards,
jaak

Hi,

I think they are refering to the native phone software. ie: it is done in the phone software. i am not sure.

A hardware implementation means that the task is covered by dedicated pieces of silicon (DSP, Microcontroller, ...) instead of a general purpose CPU running a software implementation and possibly sharing its power with other applications.

Does this means that if we are to implement a clipping algorithm in hardware,
we write the code in c or assembly and at the time of execution, the fucntion is passed from the cpu to the gpu which has spacial chips to do these things fast. If this is not the case, please tell me what is the process of implementing an algorithm in hardware.

Hi,
It can mean that programs are written by means of assembly languages on microprocessing chips and then there will be functions that can be called explicitly.

Thanks

As said, HW implementation uses some specific multimedia accelerator or DSP instead of general purpose CPU to perform the media processing. Usually the algorithms for them are implemented by the manufacturer of the device (who intergates its product from different HW and SW components) or by the provider of the specific HW for the processing.

Fetching the code to the HW accelerated media processing unit from the application is not possible in the mobile Java domain and I guess it's quite rare anyway. You would need to have the binary for some specific HW and your application would be very product specific.

Dear friends,

thanks for the reply.
