Radix-4 SRT divider
Maturity plannedTargets FPGA + ASICDifficulty HardPriority 2
Radix-4 SRT integer divider with redundant (carry-save) partial remainder and quotient-digit selection table, two quotient bits per cycle; signed and unsigned with remainder.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
