Targeting cost sensitive embedded applications in consumer electronics, MIPS Technologies had added two devices to its line of hard intellectual property (IP) cores.
According to Russ Bell, vice president of marketing at MIPS Technologies, the MIPS32 24Kc and 4KEc hard cores are designed as low cost, low-risk options
for startups, fabless semiconductor companies, and system OEMs that want to take
advantage of the MIPS 32-bit architecture in a broad range of digital consumer products.
With a worst-case frequency of 260 MHz in 10.7mm2, the 24Kc hard core is available in TSMC 180nm G process and is designed specifically for use in set-top boxes, residential gateways, digital TVs, and other high-end consumer applications.
The MIPS32 4KEc hard core, available in a TSMC 130nm G process, has a worst-case
frequency of 233 MHz in 2.5mm2, and is designed for a broad range of embedded applications, including high-performance handheld and mobile consumer devices.
Data and instruction cache sizes on the 24Kv are 16KB/16KB bytes and on the 4KEc are 8KB/8KB. Both feature a 32-entry Translation Lookaside Buffer (TLB) for Linux support, the MIPS16e ASE for code compression as well as a multiply/divide unit.
Both also feature the company’s CorExtend capability to enable customer-defined instruction extensions as well as a COP2 interface to customer-defined coprocessor. Instruction and data breakpoints are included for for debug support.
The MIPS32 24Kc and MIPS32 4KEc hard cores are now available for licensing from
MIPS Technologies. Both cores will be delivered with design kits composed of
complete product documentation, design data, verification and simulation models,
and include support and training.
