Summary The PicoBlaze ™ module is a fully embedded 8-bit microcontroller macro for the Virtex™-II series. Although it could be used for processing of data, the PicoBlaze macro is most likely to be employed in applications requiring a complex, but non-time-critical state machine. This revised version of the popular Constant (k) Coded Programmable State Machine (KCPSM) macro (PicoBlaze) has also been developed with one dominant factor being held above all others–its size. The result is a microcontroller that occupies just 84 Virtex-II slices, which is 33 % of the smallest XC2V40 device and incredibly less than 0.25 % of the XC2V6000 device. Together with this small amount of logic, a single block RAM is used to form a ROM store for a program of up to 1024 instructions. Even with such size constraints, the performance is respectable in the 40 to 70 MIPS range, depending on device speed grade
