The ARM1156T2-S and ARM1156T2F-S processors incorporate the latest ARM Thumb-2 technology for even higher code density and instruction set efficiency. Thumb-2 technology uses 31 percent less memory than pure 32-bit code to reduce system cost, while at the same time delivering up to 38 percent better performance than existing Thumb technology-based solutions. These processors also feature optional parity protection for caches and Tightly Coupled Memories (TCM), and non- maskable interrupts, making them ideal for embedded control applications where high reliability or high availability are paramount.
The ARM1156T2F-S processor includes an integrated floating point coprocessor - ideal for embedded control applications developed from mathematical models. Both processors feature an enhanced Memory Protection Unit (MPU) and offer an ideal upgrade path for embedded control applications currently using ARM946E-STM, ARM966E-STM or older 16-bit processors.
These processors feature AMBA 3 AXI specification interfaces, offering higher system bus bandwidth with fewer bus layers and rapid timing closure.
