Patent number: 11455171Abstract: A fast and frugal item-state tracking scoreboard circuit is disclosed. The scoreboard maintains per-item partial states across multiple memory circuits, enabling multiple lookups per clock cycle and multiple state updates per clock cycle. In an embodiment a scoreboard is used to schedule instructions in an out-of-order processor. Each clock cycle the scoreboard indicates the busy state of an instruction's registers and may update the busy state of the destination registers of issuing instructions and completing instructions. Applications include register tracking, function-unit tracking, and cache-line state tracking, in embodiments including processor cores (including superscalar, superpipelined, and multithreaded processors), accelerators, memory systems, and networks. In an embodiment, a register-busy scoreboard circuit is implemented using FPGA LUT RAM memory.Type: GrantFiled: May 29, 2020Date of Patent: September 27, 2022Assignee: Gray Research LLCInventor: Jan Stephen Gray
