Xilinx Introduces Zynq UltraScale+ MPSoC with Cortex A53 & R5 Cores, Ultrascale FPGA

Xilinx Zynq-7000 dual core Cortex A9 + FPGA SoC family was announced in 2012, and provides a wide range of SoC with features and price range, and led to low cost ARM + FPGA such as ZedBoard, and more recently Parallela and MYiR Z-Turn boards. The company unveiled its successor with Zynq UltraScale+ MPSoC providing five times more performance per watt, with four ARM Cortex A53 cores, two ARM Cortex R5 real-time MCU cores, a Mali-400MP GPU, an UltraScale FPGA fabric manufactured with 16nm FinFET+ process. There are two main sub-families in Zynq Ultrascale+ MPSoC for “smarter control & vision”, and “smarter network”. Both share the same processing systems (CPU, GPU, MCU, Peripherals, Security), but the networking family has beefier FPGAs, and lacks the H.264/H.265 video processing unit found in the control & vision version: Processing Systems Processor – Quad ARM Cortex A53 MPCore up to 1.3GHz Real-time Processor – […]

Cortus Introduces APS23 and APS25 32-Bit Cores for Micro-controllers

ARM and MIPS are not the only games in town with it comes to 32-bit cores for micro-controllers. I’ve already written about Beyond Semiconductor, and mentioned Andes used in some Wi-Fi SoC, and today I’ve come across another IP company called Cortus. which just introduced APS23 and APS25 cores based on their latest Cortus V2 instruction set. which offers a smaller code footprint compared to there V1 ISA. APS23 can achieve 1.44 Coremarks/MHz, 2.83 DMIPS/MHz, and can run up to 200 MHz when manufactured with 90nm process, whereas APS25 is a bit more powerful with 2.09 Coremarks/MHz, 2.36 DMIPS/MHz, and can run up to 344 MHz. Minimal power consumption is 11.6 and 19.3 uW/Mhz for APS23 and APS25 respectively. Key features of both cores include: APS23 APS25 Excellent Code Density 3 stage pipeline 5-7 Stage Pipeline Sequential Multiplier High Performance Integer Multiply Optional Parallel Multiplier (Gives 2.62 Coremakes/MHz) Integer Divider Full Peripheral Set Dual […]
