Description
The SuperNOVA included a number of improvements that dramatically improved performance over the original model. This included the use of ROM for library software that could be run much faster than the same code in the normal core memory, due to the latter’s need to be written immediately after being read. Additionally the system included a new set of core with an 800 ns cycle time, faster than the original’s 1200 ns version. Finally the SuperNOVA also replaced the earlier model’s 4-bits-at-a-time math unit with a new 16-bit parallel version, speeding math by up to four times.
