Functional Safety Solutions for the Industrial Field In the industrial equipment field the importance of “functional safety,” which aims to maintain safety even when malfunctions occur, is increasing as a way to prevent the adverse effect of breakdowns and accidents on plant operation, the adverse effect of injuries to personnel on society, and the associated economic losses. The European Union’s Machinery Directive also requires that equipment meet functional safety standards. To reduce the development burden on customers as the application of functional safety standards expands within many industrial...

RX Core Features RX Core Roadmap Feature 1 New-Generation CPU That Inherits the Strengths of Its Predecessors As products gain added value and systems become more complex, customers demand ever higher performance from microcontrollers. At the same time, they require microcontrollers with low power consumption to improve energy efficiency and extend battery life. The new RX core incorporates advances designed to meet these needs. It is called the RXv2 core. The RX core combines the strengths of the CISC architecture of the H8S, H8SX, M16C, and R32C families and the agility of the RISC architecture...

Feature 4 Revised Instruction Set RXv2 Core: CPU Block Diagram With regard to basic instructions and addressing modes, the number of instructions and the code size where reduced by identifying the most frequently used instructions and addressing modes and assigning them the shortest formats. Also, additional enhancements to the addressing modes were made to increase the efficiency of table manipulation. Instruction frequency analysis Transfer 31% The RXv2 core maintains compatibility with the RXv1 core while providing the following enhancements: Subroutine branch Conditional Compare branch 8%...
