The best performance can be typically achieved by a dedicated hardware solution, while a faster design and a less expensive solution are commonly achieved by software based solutions. A bus will either carry 8 bits or 16 bits overall. Such buses are made up of 8, 16 or more wires. Bus: Fundamentally, Bus is a set of wires that serve as a contact channel or a transfer data medium. Introduction Typical digital systems consist of hardware components and/or software components executing on dedicated processors. The 8051 microcontroller includes 4K code memory or program memory, so it has 4KB ROM and 128 bytes of data memory (RAM) as well. The system proposed provides a suitable environment and an efficient solution for rapid prototyping and low cost small series production of low to medium complexity embedded digital systems. co-synthesis is guided by constraint directives added to the software-based system specification. The target architecture integrates a parameterizable 8 bit RISC microcontroller core with application specific hardware functional units able to accelerate the execution of the timing critical system components. : This paper describes a co-synthesis environment for the implementation of embedded digital systems on a single chip quick turnaround sea-of-gates technology.
