![]() With all these features like high performance, scalability, and adaptability (both in terms of cost and capacity), versatility (used in commercial, technical, military, and aerospace applications), incorporated OOPS (object-oriented programming) features, and open source, SPARC is available for licensing to any individual in addition to the microprocessor manufacturers. Due to its highly scalable open architecture, SPARC focuses on optimizing compilers and creating effective pipelines for hardware executions. SPARC is based on load-store-type architecture and supports 32-bit and 64-bit instructions. SPARC (Scalable Processor Architecture) processors are also a part of the RISC architecture-based family developed by Sun Microsystems. Due to its decent performance and low power consumption, ARM chips are commonly used in smartphones, laptops, tablets, desktops, and the world’s fastest supercomputer (Fugaku). ARMv8 is the first ARM architecture that includes 64-bit addressing, enabling processors to combine 64-bit execution with 32-bit execution. Before ARMv8, all architecture designs are based on 32-bit addressing. ![]() licensed these architectures to several semiconductor companies so that they incorporate these designs into their products.ĭifferent generations of ARM architecture designs support 32-bits and 62-bits, including ARMv1, ARMv2, ARMv3, ARMv4, ARMv5, ARMv6, ARMv7, ARMv8, ARMv8.1, ARMv8.2, ARMv8.3, ARMv8.4, ARMv8.5, ARMv8.6, ARMv8.7, ARMv9, etc. ARM-based on load-store architecture (i.e., load and store can occur between memory and registers) type has a set of rules and instructions which defines the interaction between hardware and software. ARM architecture supports 32-bit and 64-bit memory addresses. It is proprietary-based and owned by ARM Ltd. Some of the RISC processor designs are described in the following sections:ĪRM (Acorn RISC Machine) is a part of the RISC architecture-based family known for its processors and cores. But in the case of open-source RISC architecture-based processors, designers can implement their design as per standards. Any programmer or designer wanting to integrate proprietary-based processors into their designs must pay royalties to a particular company. Most RISC architecture-based processors are proprietary-based, and some are based on an open-source environment. There are different types of RISC processor designs based on their architectural styles, which are listed below: Accordingly, RISC architecture-based processors are commonly used in the lap, mobile phones, tablets, desktops consoles, supercomputers, and many smart devices used in automotive systems, home networking, and wireless technologies. High-level language compilers can also create efficient code due to the capabilities of a small set of instructions in RISC architecture. With all these features, the power consumption is also significantly less, and the overall performance of RISC processors is highly improved. Due to these reduced instructions, RISC architecture requires fewer transistors in hardware space while leaving more space for general-purpose registers. ![]() They can support a greater number of registers (simple decoding logic), resulting in less time for memory loading/storing and a reduced instruction set (lesser number of bits used for opcode). RISC processors can have simple addressing modes, fewer data types, etc. ![]()
