 In 2000, Castle released "Kinetic", a new StrongARM processor board with its own onboard memory slots augmenting main memory, reducing the need to negotiate the slow front side bus for memory accesses.The podule bus on the RiscPC (i.e.32-bit; predecessor systems to the RiscPC had 16-bit bus) can achieve a maximum data throughput of approximately 6100 KByte/s.
