CISCarkkitehtuurit

CISCarkkitehtuurit, which translates to CISC (Complex Instruction Set Computer) architectures, represent a fundamental design philosophy in computer processor design. Unlike RISC (Reduced Instruction Set Computer) architectures, CISC processors are characterized by a large set of instructions, many of which are complex and can perform multiple low-level operations within a single instruction. This complexity allows a single CISC instruction to achieve what might require several RISC instructions. The aim of CISC is to reduce the number of instructions needed for a program to execute, thereby simplifying the compiler's task and potentially reducing program size. Early computers heavily utilized CISC designs, and they remain prevalent in many modern systems, particularly in the x86 architecture found in most personal computers and servers. The trade-off for this complexity is that individual instructions can take many clock cycles to execute, and the hardware required to decode and execute these complex instructions is often more intricate. Despite the rise of RISC, CISC architectures continue to evolve, incorporating features and optimizations to maintain performance and efficiency in diverse computing environments.
