10.3. Performance and Data Throughput

The following table gives the data transfer rates between different memory, processor and interface resources on the Monaco board. Monaco boards using the TMS320C6201 processor have a clock speed of 200 MHz; Monaco67 boards using the TMS230C6701 processor have a clock speed of 167 MHz.

		Clock Speed		Units
Source	Target	200	167	MHz	Comment
‘C6x	Local SBSRAM	400	333	MB/s
	Local SDRAM	400	333	MB/s
	PEM Site	400	333	MB/s
	Global SRAM read	88	74	MB/s
	Global SRAM write	100	83	MB/s
	DSP~LINK3 Standard	15	12.5	MB/s
	DSP~LINK3 Standard Fast	28	24	MB/s
	Hurricane Registers	115	138	ns
	VMEbus (master) read		2	MB/s	Coupled read. Typical value for a "real" slave, which is slower
					than for an "ideal" VME slave.
	VMEbus (master) write		9	MB/s	De-coupled write. Typical value for a "real" slave, which is
					slower than for an "ideal" VME slave.
VME Host	Global SRAM		40	MB/s
	Hurricane Registers		150	ns
	HPI read		14	MB/s	Maximum speed from internal ‘C6x memory when the ‘C6x is
					not accessing memory
	HPI write		28	MB/s	Maximum speed to internal ‘C6x memory when the ‘C6x is not
					accessing memory.
