EP140 AMBA AHB Bus Slave

Features

• Supports AHB bus interface to the ARM CPU.
• User interface designed for high speed access to two sets of on-chip or off-chip modules.
• Four write buffers to process posted write.
• Dual read buffers to process CPU read.
• Read access to external bus handled as delay read to avoid system deadlock.
• Supports burst transfer and zero wait state to maximize data bandwidth.
• Supports data width of 8, 16 and 32 bits.
• Supports burst transfers up to 16 words of data.
• Supports early burst termination and CPU master busy.
• Multiple bus slave is supported by Ready signal input and outputs.
• Programmable address mapping to multiple address spaces.
• User interface optimized to access secondary bus such as PCI and memory subsystems based on SDRAM and FLASH.
• Optimized for ASIC and PLD implementations, including Excalibur PLD.
