Finite state machines are widely used in digital circuit designs. Generally, when designing a state machine using an HDL, the synThesis tools will optimize away all states that cannot be reached and generate a highly optimized circuit. Sometimes, however, the optimization is not acceptable. For example, if the circuit powers up in an invalid state, or the circuit is in an extreme working environment and a glitch sends it into an undesired state, the circuit may never get back to its normal operating condition.

文章提出了一種精簡(jiǎn)指令集8 位單片機(jī)中, 算術(shù)邏輯單元的工作原理。在此基礎(chǔ)上, 對(duì)比傳統(tǒng)PIC 方案、以及在ALU 內(nèi)部再次采用流水線作業(yè)的332 方案、44 方案, 并用Synopsys 綜合工具實(shí)現(xiàn)了它們。綜合及仿真結(jié)果表明, 根據(jù)該單片機(jī)系統(tǒng)要求, 44 方案速度最高, 比332 方案可提高43.9%, 而面積僅比最小的332 方案增加1.6%。在分析性能差異的根本原因之后, 闡明了該方案的優(yōu)越性。關(guān)鍵詞: 單片機(jī), 精簡(jiǎn)指令集, 算術(shù)邏輯單元, 流水線 Abstract: Work principle for ALU in an 8_bit RISC Singlechip microcomputer is described. The traditional PIC scheme, 332 Pipeline scheme and 44 Pipeline scheme are compared on the base of the principle, which are implemented using Synopsys design tools. Results from synThesis and simulation shows that 44 scheme operates the fast, which is 43.9% faster and only 1.6% larger than 332 scheme. The essential reason why the performance is so different is analyzed.Then the advantage of 44 scheme is clarified.Key words: Singlechip, Microcomputer, RISC, ALU, Pipeline

The GRLIB IP Library is an integrated set of reusable IP cores, designed for system-on-chip (SOC) development. The IP cores are centered around the common on-chip bus, and use a coherent method for simulation and synThesis. The library is vendor independent, with support for different CAD tools and target technologies. A unique plug&play method is used to configure and connect the IP cores without the need to modify any global resources.
