Fourth Generation Microprocessor :
The single chip 32-bit microprocessor was introduced in 1981 by Intel as iAPX 432. The other 4th generation microprocessors were; Hewlett-Packard, Bell Single Chip Bellmac-32 , Texas Instrument99000, National NSl 6032, Motorola 68030 and 68020.
The power of the microprocessor went on increasing with the advancement in the integrated circuit technology. The VLSI technology culminated in the extremely complex microprocessor with as many as one billion transistors on a single chip. The Intel in the year 1985 announced the 32-bit microprocessor (80386). The 80486 has already been announced and is also a 32-bit microprocessor.
Mostly microprocessors were manufactured with HMOS (high density short channel MOS) technology because of the following benefits:
(i) Speed-power product was 4-times larger than NMOS. It's typical value was I-pico joule where as in the case of NMOS technology it was 4-pico joules.
(ii) Circuit density was roughly 2-times greater than NMOS. The typical NMOS density was 4128 um2 gate whereas it was 1852.5 um2 for HMOS
Problem (a) Prepare the assembly code sequence for each of the four styles (accumulator, memory-memory, stack, load/store) of machine for the code fragment: A = B + C;
NAME : Logical Name of a Module: The NAME directive which is used to assign a name to an assembly language program module. The modulecan now be mention to by its declared name.
Machine Coding the Programs So far we have describe five programs which were written for hand coding by a programmer. In this, we will now have a deep look at how these prog
