His latest post doesn’t disappoint and shows how he uses the CORDIC algorithm to generate very precise sine and cosine waves in VHDL. CORDIC (Coordinate Rotation Digital Computer; sometimes ...

However, determining these polar coordinates relies on the COordinate Rotation DIgital Computer (CORDIC), a power-hungry circuit block. CORDIC generates multi-bit amplitude and phase signals that ...

Its floating point unit (FPU) was a big improvement over its predecessors that still used the venerable CORDIC algorithm. In a recent blog post [Ken Shirriff] takes an up-close look at the FPU and ...
