Both the energy consumption and the propagation time delay are very critical parameters of contemporary integrated circuits. It is obvious that a circuit should consume energy as small as possible and ought to work with maximum speed and efficiency. However, these parameters are dependent on temperature, which can change with both external (e.g. high(More)
The paper presents a prototype at 8-bit RISC microcontroller, called OctaLynx, with 16-bit address bus. It consists of the core (with instruction decoder, arithmetic logic unit and interrupt control unit) and some peripherals (three 8-bit general purpose input-output ports, timers/counters, USART, SPI). The prototype uses external memory. The OctaLynx(More)

The paper presents techniques of dynamic control of digital integrated systems performance considering die temperature. The dynamic clock throttling (DCT) and the dynamic frequency scaling (DFS) are taken into account. Allowing for the power-time product (pt) a new predictive method that improves the efficiency of DCT and DFS techniques is introduced
The paper presents new supervisors dedicated to predictive methods of dynamic power management, i.e. DCT (dynamic clock throttling), DFS (dynamic frequency scaling), and DVS (dynamic voltage scaling). The presented supervisors make decisions on the basis of current chip temperature; future, current and previous power dissipations. They consist in(More)
In this paper, we describe the parameters identification results of PTAT (proportional to absolute temperature) temperature sensors that are implemented in the test chip and dedicated to CMOS integrated circuits. Theirs principles of operation are based on the vertical PNP structure. These sensing elements are uniformly distributed on the chip surface. The(More)
The paper describes design and structure of the Temperature-Controlled Oscillator for high frequency processors which work is based on information of present chip temperature. The task of the circuit is to stabilise required value of temperature of the silicon die and ensure safe work of the processor. The circuit consists of: temperature sensor, ring(More)
The paper describes features of the OctaLynx RISC microprocessor version dedicated to cooperation with the Dynamic Power Management system with awareness of present circuit temperature. The processor can use two independent interrupts triggered by thermal events. Additional function registers contain information about maximum temperature found in the(More)
In this paper, a Temperature-Controlled Oscillator (TCO) dedicated to method of optimum control of throughput (OCT) of microprocessor is introduced. The aim of this device is to control the efficiency of computing machine in such a way that its internal temperature is maintained on required level. The TCO is analytically modeled and simulated in Simulink.(More)
This paper presents a maximum temperature selection circuit that cooperates with a set of temperature sensors. Two different types of temperature sensors are used: proportional to absolute temperature PTAT which uses bipolar structures and CMOS one which uses thermal dependencies of MOS transistors. This circuit is dedicated to implementation of method for(More)
