Force-System Resultants and Equilibrium

We can further classify instructions in terms of the number of explicit operands, operand locations, and type and size or the operands. Instructions architecture that specifies no explicit operands is better known as stack architecture. In stack architecture all operations are performed on the data that are on the top of the stack. Examples of stack architecture are HP 3000/70 by Hewlett-Packard and B5500 by Burroughs. In the accumulator architecture, all operations are performed between the operand specified in the instruction and the accumulator, which is a special register. An example of accumulator architecture is the PRISC processor shown in Figure 143.1. One of the well-known accumulator-based architectures is PDP-8, by Digital Equipment Corporation. Almost all modern machines have a repertoire of available general-purpose registers whose numbers range from 16 to 32 and in some cases even more than 32 (SPARC). The number of operands explicitly specified in the instructions of a modern architecture today can be two or three. In the case of three operands, an instruction explicitly specifies the location of both operands and the location where the result is to be stored. In some architectures (e.g., IBM System/360),
The CPU

The accumulator functions both as a source and as a destination register for many of the basic microprocessor operations. As a source register it contains the data that will be used in a particular operation, while as a destination register it will be used to hold the result of a particular operation. The accumulator (or A register) features in a very large number of microprocessor operations, consequently more reference is made to this register than any other.

The electricity cost (Ec) consumed by HSED involves only the cost of powering the electric heater per hour since the axial fans and other electrical components are powered by a DC. accumulator. The amount of energy consumed is calculated thus (Ndukwu et al. 2020):
