Processor Performance

The problems of creating of high-performance embedded computing systems based on microprocessors KOMDIV is considered. Processor performance is dependent upon three characteristics: clock cycle, clock cycles per instruction, and instruction count. These characteristics for microprocessors KOMDIV are optimized using parameter performance/power consumption and requirements of embedded systems.

Battery Technology

Majority of the devices that are used in ubiquitous computing are expected to be as small as possible, be able to perform as many computations as possible, and transmit the results to another device or computer. Such expectations in performance put a pressure on the power budget of such devices. It is a well-known fact that the advances in battery technology are much slower and cannot keep up with the performance demands of tiny gadgets unless new methods of designing and managing hardware and software are developed and used. This chapter will introduce the motivation for low power design considerations by discussing the power limitations of ubiquitous computing devices. Then the chapter will discuss the research directions that are being pursued in literature for reducing power consumption and increasing efficiency of ubiquitous computing systems.

Complex Problems

At present, digital signal processing involves enormous amounts of computations with large-bit arrays, which are carried out in real time. In connection with the need to solve more and more complex problems, constantly growing requirements are imposed on the main parameters of digital processors (speed, reliability, power consumption, etc.), which determine the computing capabilities of systems with digital signal processing. In turn, the rapid development of microelectronics, its successes make it possible to create more and more high-performance computing systems, which makes it possible to solve more and more complex problems, including in the military sphere. The production of the latest information technology means is a technological task that can be solved exclusively by economically developed countries. Bringing domestic microelectronics to the current world level requires significant investments. Therefore, the study and research of discrete nodes and devices is of the direct practical importance. When developing promising computers, new technological approaches should be applied: minimizing power consumption, maintaining modularity and high computational density within a single node, creating high-speed data transmission with the lowest delays, creating an efficient storage system, and choosing the best types of memory. One of such possible approaches is the use of a non-positional form of information presentation in computing systems for national and military purposes. This gives a number of advantages, the main ones of which are: a decrease (by orders of magnitude) in the hardware volume of computing devices, an increase in the speed of calculations, an increase in the noise immunity of communication channels. To use the above method, it is proposed to include a probabilistic arithmetic device in the information processing device that performs basic arithmetic operations (addition, multiplication, exponentiation, subtraction, division), which are performed without the use of additional algorithms and mechanisms, in contrast to “classical" digital representation of binary information, where all operations are performed on the basis of the addition operation.
