摘要： A processor natively executes lookup instructions. The lookup instruction is decoded to determine which general-purpose register (GPR) contains a pointer to a lookup key in a buffer. A variable-length key is read from the buffer and hashed to generate an index into a first-level cache and a hashed tag. An address of a bucket of entries for the index is generated and tags from these entries are read and compared to the hashed tag. When an entry matches the hashed tag, a second-level entry is read. A stored key from the second-level entry is compared to the input key to determine a match. The addresses of the matching second-level and first-level entries are written to GPR's specified by operands decoded from the lookup instruction. When the key or entry data is long, the second-level entry also contains a pointer to a key extension or data extension in a third-level cache.

摘要： A copy instruction executed by a functional-level instruction-set computing (FLIC) processor copies a variable-length data block from one resource to another resource through a cross-bar switch. Resources include general-purpose registers, input, output, and execution buffers, DRAM, SRAM, and other memory. A copy-with-validate instruction has an operand pointing to a first rule in an immediate rule table. The first rule controls validation of a first data-item in the data being copied. Validation includes range and equality checking of the data-item. The value of the data-item or the current offset can be written to a register. A format field in the rule indicates the size of the data-item, or the size is read from the data-item for variable-size formats. The current offset is incremented by the size. The next data-item is validated by a next rule, and other rules in the immediate table control validation of other data-items in the data block.
