Advanced RISC Machines Ltd has introduced three new additions to its ARM7 32-bit microprocessor core family, which the Cambridge, UK company claims makes it easier for system designers to implement complex systems. The ARM740T, ARM720T, ARM720T have been designed to enhance the low-cost and low power consumption of the ARM7TDMI microprocessor core. ARM has added an 8Kb cache and write buffer to minimize external memory access, which enables the use of low cost Random Access Memory without losing performance. The system bus and external memory can then operate at lower speeds than the processor which reduces power consumption. The ARM740T has been designed with embedded system application in mind, simplifying the development of embedded applications such as modems and set top boxes. The ARM710T is for use with internet applications and Personal Digital Assistant devices and enables the use of operating systems such as EPOC32 from Psion Plc. It has full Memory Management Unit functionality which enables the safe use of code downloaded from a network such as the internet. The ARM720T is for use with Microsoft Corp’s Windows CE operating system used in devices such as set top boxes, smart phone and mobile personal digital devices. All the new members of the family are available for licensing now.
