CAST CPXP-EPX8 Core — ASIC Implementation Results

The following sample results were obtained at the required frequency of 250 MHz, and with a single Virtual Channel (VC0), Maximum Payload of 256B, a 4kB Retry buffer, a 4kB Receive buffer, no ECRC, and using a generic Application Interface.

Link Width Technology Approx. Area
x8 TSMC 0.13 µm 77,600 gates
x8 TSMC 0.18µm 83,700 gates
x8 TSMC 0.90 µm 65,000 gates

The core includes an SoC bus bridging module (AIF), an additional subsystem that may be used to integrate the core with SoC designs using custom or various standard interfaces. The sample implementation results shown below show the additional gates needed for an AMBA™  AXI with two DMA channels.

DMA Channels Technology Approx. Area
2 DMAs TSMC 0.13 µm 23,500 gates
2 DMAs TSMC 0.18µm 22,900 gates
2 DMAs TSMC 0.90 µm 20,000 gates
