Structural decomposition of microprogrammed controllers

Wiśniewski R., Barkalov A.

Electronics and Telecommunications Quarterly

2009

Vol. 55, No 2

215-241

The paper focuses on the structural decomposition of control units. Eight methods of compositional microprogram control units are described and compared. Proposed solutions can be divided into two main groups. The first one deals with CMCUs with mutual memory, where the internal code of the controller is recognized by the microinstruction address. The second group of presented methods is based on control units with sharing codes, where the microinstruction address is formed as a concatenation of codes generated by the counter and by the register. The aim of all proposed solutions is to reduce the number of logic blocks of the destination programmable device.

Optimization of compositional microprogram control unit by modification of microinstruction format

Titarenko L., Bieganowski J.

Electronics and Telecommunications Quarterly

2009

Vol. 55, No 2

201-214

The methods of hardware amount decrease are proposed oriented on implementation of compositional microprogram control unit with PAL macrocells and embedded memory blocks of CPLD - based SoC. First method is based on introduction of additional microinstructions. Second method is based on expansion of the format of microinstructions. In both cases amount of EMBs is minimal one. The examples of application of proposed methods are given.
