8-bit core with high-speed processing

4 October 2006 DSP, Micros & Memory

Toshiba has developed an 8-bit microcontroller (MCU) core capable of processing one instruction cycle in a single clock cycle. Designated TLCS-870/C1, the new core enables faster processing at lower frequencies, reduced noise and lower power consumption compared with Toshiba's previous 8-bit core, it says. The core architecture was modified from the previous TLCS-870/C architecture to achieve the fast processing - an up to four-fold increase in performance at the same clock frequency. Part of the IC design used synchronous RTL design instead of multiphase-clock design based on circuit diagrams. The expanded address space (up to 128 KB) was attained with a memory-management method that manages code and data in separate areas. The TLCS-870/C1 core is binary compatible with previous Toshiba 8-bit MCUs; so, existing software resources can be used. This flexible core is suited for a wide range of applications from small-scale, to large-scale applications requiring large-capacity ROM, such as airconditioners, washing machines, and other white goods.
