Unreferenced date November 2006 An applicationspecificstandardproduct or ASSP is an integrated circuit that implements a specific function that appeals to a wide market. As opposed to Applicationspecific integrated circuit ASIC s that combine a collection of functions and designed by or for one customer, ASSPs are available as off the shelf components. ASSPs are used in all industries, from automotive to communications. Examples of ASSPs are integrated circuits that perform video and or audio encoding and or decoding.

An applicationspecific instruction set processor ASIP is a component used in system on a chip design. The instruction set of an ASIP is tailored to benefit a specificapplication. This specialization of the core provides a tradeoff between the flexibility of a general purpose Central processing unit CPU and the performance of an ASIC . Some ASIPs have a configurable instruction set. Usually, these cores are divided into two parts static logic which defines a minimum ISA instruction set architecture and configurable logic which can be used to design new instructions. The configurable logic can be programmed either in the field in a similar fashion to an FPGA or during the chip synthesis.

Specific force is defined as the non gravitational force per unit mass . math mbox Specific Force frac mathrm Force non gravitational mathrm Mass math Specific force also called g force and mass specific force is measured in Metre per second squared meters second m s sup 2 sup which is the units for acceleration. Thus, specific force is not actually a force, but a type of acceleration. However, the mass specific force is not a coordinate acceleration, but rather a proper acceleration , which is the acceleration relative to free fall. Forces, specific forces, and proper acceleration s are the same in all reference frames, but coordinate accelerations are frame dependent. For free bodies, the specific force is the cause of, and a measure of, the body s proper acceleration . The g force acceleration is the same as the specific force. The acceleration of an object free falling towards the earth depends on the reference frame it disappears in the free fall frame, also called the inertial frame , but any g force acceleration will be present in all frames. This specific force is zero for freely falling objects, since gravity acting alone does not produce g forces or specific forces. Accelerometers on the surface of the Earth measure a constant 9.8 m s 2 even when they are not accelerating that is, when they do not undergo coordinate acceleration . This is because accelerometers measure the proper acceleration produced by the g force exerted by the ground gravity acting alone never produces g force or specific force . Accelerometers measure specific force proper acceleration , which is the acceleration relative to free fall, ref www.strapdownassociates.com Accels 20Measure.pdf ref , not the standard acceleration that is relative to a coordinate system.
